Development Update: Ver0.43 Coming Soon!

Hello everyone, this is LactoQuest.

This past week, our illustrator Tsunamikan-sensei has been working tirelessly. Not only has the planned CG set for Ver0.4 been completed, but additional new content has also been added. On top of that, we’ve carefully adjusted some of the CGs based on your valuable feedback, ensuring that the overall style remains consistent.

I’m very happy to announce that Ver0.43 is scheduled for release at the end of this month!
This update will include 6–7 new CG sets, along with the introduction of brand-new features that have never appeared in the game before. We hope you’ll look forward to experiencing them.

At the same time, I’m also tackling another important task that I’ve been putting off for too long: performing a complete tri-language (Japanese, Chinese, and English) revision and integration of my previous work, Her Fall in the Last Days, as well as fixing many bugs. That title was created back when I had no experience, and in many ways the writing and structure are rough to look back on. However, since it’s deeply connected to the story and world of this series, leaving it as-is would be irresponsible.

Once the integrated version is complete, I plan to relaunch it on additional platforms, so I’d be very grateful for your continued support when the time comes.

Lastly, this post also includes samples of CG revisions made according to your feedback.
Thank you again for always supporting us—we’ll continue doing our best to meet your expectations!

Stigma of Corruption: Nightbound Courier — Production Resumes

Hello everyone, this is LactoQuest. Today I’d like to share some exciting updates.

CG Production Back on Track

First of all, I’m happy to introduce a new partner to the team — 缶詰ツナ味.
He has officially taken over the CG work for Stigma of Corruption: Nightbound Courier.

• Twitter: https://x.com/aki_hikky

• FANBOX: https://www.fanbox.cc/@aki-hikky

Right now, 缶詰ツナ味 is working on the Ver.0.4 CGs while also tackling unfinished variation tasks left from before. The workload is quite challenging, so the overall style is still in the process of fine-tuning. That said, I’m already very satisfied with the results so far.

I’d really appreciate it if you could support Kanazume Tuna-aji as well! If you’re interested in his portfolio and illustrations, I highly recommend subscribing to his FANBOX to enjoy more of his amazing work and help support his creations directly.

Progress on the Side Story

As for the Her Fall in the Last Days side story:

• Total CGs: about 12

• Progress: around 80% of the CGs completed, overall progress at 68%

This side story builds on the original narrative with some revisions and upgrades. I’ve been trying to add more emotional ups and downs, so it won’t just feel like a bonus episode, but rather a more heartfelt experience.

Next Steps

In early September, I just moved from Canada to Tokyo, so I’ve had a lot of personal matters to take care of. Still, I’ll do my best to push development forward in parallel with daily life, with the following priorities:

1. Ver.0.4 — the current top priority.

2. Side Story — targeted for release in November.

3. Stigma of Corruption: Nightbound Courier — once the above are completed, I’ll devote full focus to it.

Once again, thank you all so much for your encouragement and support. Every follow, comment, and subscription gives me the strength to keep creating. I hope you’ll continue to stay with me as we bring these projects to completion together!

Her Fall in the Last Days: Gaiden Development Update

Hello everyone, this is LactoQuest.

I am currently focusing on the development of Her Fall in the Last Days: Gaiden.
As for Stigma of Corruption: Nightbound Courier, we are still in the process of searching for a suitable illustrator. Development is continuing, but until we find the right partner, I will be putting more effort into the production of the Gaiden.

Thank you very much for your constant support. I strongly believe that only by working harder and dedicating myself fully to the production can I live up to your expectations.

In this article, I would like to introduce some new characters that will make their debut in the Gaiden. They will not only appear in this side story, but will also become the main characters in Her Fall in the Last Days 2, where even more intense and dramatic NTR stories will unfold.

Character Introductions

• Rinko
  She met Akito through an arranged marriage and eventually married him. Rinko is a gentle, devoted, Yamato Nadeshiko-type woman. Before marriage, she worked as a private tutor, but she quit after marrying. While blessed with an extremely voluptuous figure—which often troubles her—she is nonetheless admired by many. Because her husband has been constantly busy with work, they have not had children, and their married life has lacked intimacy for more than six years, leaving her in a state of deep sexual frustration. In reality, she often relies on a vibrator to soothe her loneliness.

  

• Remy
  Unemployed and a gang member. His older brother works for a pharmaceutical company in the United States. Remy himself has a powerful build and once competed in state-level bodybuilding contests. Though he had a promising future, an unfortunate injury forced him to retire. He later spent many years as a bodybuilding trainer. What he is most known for, however, is his extraordinary physical endowment. Women who have been with him never forget the experience.

These characters will be officially introduced in the Gaiden and will also serve as the protagonists in Her Fall in the Last Days 2, where more layered and tension-filled NTR stories will unfold. I hope you will continue to look forward to them, and once again, thank you for your unwavering support.

Regarding Development Progress and Compensation

Hello everyone, this is LactoQuest.

I regret to inform you that, due to certain circumstances, my collaboration with illustrator Mao has come to an end. Unfortunately, I am unable to fully carry on the existing art style by myself. This means that CG production will be temporarily suspended, which will also cause delays in the overall development progress.

However, please rest assured that the story and gameplay development will continue as planned. At the same time, I have already reached out to several illustrators and will do my best to find someone who can carry on the current style so that the project can get back on track as soon as possible.

During this period, I will be focusing more time on Her Fall in the Last Days side story. Once completed, it will be given for free to all supporters as compensation and a token of my gratitude.

Additionally:

The subscription channel has been closed.

After completing the Her Fall in the Last Days side story in November, I will deliver compensation to everyone who has supported the project, based on the subscription list at that time.

If CG production resumes, I will immediately release Ver 0.4 for free.

I am truly sorry to bring you such disappointing news. I feel deeply guilty for letting down the expectations of so many supporters. Yet it is your encouragement that keeps me going, and I will continue to give my best.

For now, I will take some time to calm down, reflect, and carefully plan the future steps, so that development can return to the right track as soon as possible.

Once again, please accept my sincerest apologies.

Ver 0.4 CG Early Preview

Since I can’t include R18 content in public posts on Patreon or share certain development-related videos, the latest development updates can only be viewed on Ci-en.
Thank you all for your continued support—I’ll keep giving it my best

Early previews of CGs and their scrapped versions

The carriage CG has finally been completed!
This scene will appear in the latter half of the “Hawkpeak Fortress” chapter.

We’ll also be sharing a previously scrapped carriage CG.
Although we were quite fond of that version as well, it had to be cut due to changes in direction and scene composition. It’s a shame, really—the quality was great.

We hope you enjoy both versions, each with its own unique atmosphere!

Multi-Route System Now Implemented

Hi everyone, this is LactoQuest.

We’re thrilled to announce that
Stigma of Corruption: Nightbound Courier Ver 0.35 is finally live!

This version offers about 2 hours of gameplay.
After multiple rounds of testing and polish, we've completed the foundational system and core event framework.

That said, I personally feel it’s still not enough.
Future versions will continue expanding content and improving the gameplay experience, including:

• Fast travel to herb gathering points and key locations

• Streamlined pacing and improved controls

Due to time constraints, some of these features will be added gradually in future updates.
We appreciate your understanding and patience!

✦ Highlights of Ver 0.35

This update establishes the core systems and world structure.
At the end of the prologue, the story branches into three main paths:

• Dragon Route (Pure Love): A grand and gentle story arc, soon to dive into a “Prison” setting

• Craig the Merchant Route: A corruption route set along a journey, featuring scenes on carriages, inns, and shadow shows

• Muan the Blacksmith Route: A wild, desire-driven path set in campgrounds and the wilderness

Each route features unique maps, CGs, and custom events, providing a true divergence in gameplay.

In fact, thanks to player choices in the prologue, there are up to six path variations—some overlapping, others completely unique.

✦ On Pacing & Narrative Direction

As a developer, creating this demo has been an intense challenge.
The prologue needed to present a believable world filled with tension, and plant key narrative seeds.

That’s why I poured so much effort into the story and event sequences.
However, it also made me reflect:

"Did all this setup compromise the gameplay?"

My answer: No.

Still, I recognize that some parts might feel slow.
This was done deliberately to build the world—and partly because I was simply exhausted after so much writing.

To deliver strong emotional twists later, the prologue must firmly establish its setting and character dynamics.

So I sincerely ask for your feedback after playing.
Every comment you leave will directly shape the pacing and content of future updates.

✦ What’s Next: Future Plans & Bonus Version

The current demo ends with your departure from Dawn Village.
Next, the main story will focus on bonding with the heroine of your chosen path.

Each route will explore deepening relationships, emotional shifts, and much more intense H scenes and CGs.
Unlike the prologue, the story will no longer dwell on background or world-building.

Still, knowing that some players crave more… provocative content—
We’ve decided to release a special bonus version (Ver 0.4):

It will preview one route's core “corruption arc” in full,
including formal H scenes, corruption progression, and full CG sequences.

You’ll get a taste of what the real gameplay loop feels like post-prologue!

Let us know which route you'd like to see first via the survey link.

Vote link: https://ci-en.dlsite.com/creator/24720/article/1526132

Ver 0.35 is just the beginning.
We’ll keep working hard to deliver a dark, emotional, and truly unique gameplay experience.

You’ll soon be able to download the game for free via the DLsite preview page.

If you’ve already canceled your subscription, feel free to contact me directly for the download link.
If you haven’t subscribed yet, stay tuned for the upcoming DLsite release!

Thank you all so much for your continued support.

Early Preview of Side Story & New CGs 4

Here are some recent drafts. I'm sorry for not updating on Patreon lately. Last mon, my account was reported because I included NSFW images in a public post, which resulted in some temporary restrictions. Things have improved since then, but I can no longer share explicit content in public posts.

I expect to finish the content for the 0.3 update within the next couple of days. However, considering the time needed for translation and testing, the new version will be released on the 15th.

Additionally, version 0.35 will be released on the 25th, which will mark the completion of the demo and the start of full-scale development.

Thank you all for your continued support. I hope you’ll understand that certain images will only be shared in private or supporter-only posts moving forward.

[Demo 0.2 Bug Fix Report]

Thank you all for your continued support and feedback. I've fixed the following issues based on recent reports:

• Fixed a bug where certain events would incorrectly teleport the player to the gallery

• Fixed a bug where the village chief constantly showed an exclamation mark

• Fixed tile display errors in the box-pushing area

• Added a temporary option to remove the heroine from the party at rest points to prevent potential bugs

Plz replace the files with the same name in your game folder when updating.

If you encounter any other issues, feel free to leave a comment or message me. I'll continue to fix and optimize the game.
Thanks again for your support and patience!

----------------------------------------

I've re-uploaded the patch. I'm sorry that the previous one didn't work—apologies for the trouble caused.

"Stigma of Corruption: Nightbound Courier"Demo 0.2 Update Complete

Hello everyone, this is LactoQuest!

Demo 0.2 is now officially complete and released!

This update adds 6 new CG sets and 5 events, all focused on Kare.

If you’ve already played Demo 0.1, simply download the new version to continue—no need to restart your save.

We’ve also fixed the bugs that were reported in Demo 0.1. However, some system optimizations and status display features are still pending. These will be addressed gradually during the development of the full version.

🛠 Upcoming Development Plans:

• Early July: Demo 0.3 release, featuring Lilian’s storyline

• Mid-July: Launch of the DLsite preview page, where you can directly download and play Demo 0.3

• After that: The game will move into full-version development, with much faster progress than the demo phase—stay tuned!

Thank you so much for your continued support and patience.
Every kind word and every like from you is the driving force that keeps me creating.

-------------------------------

Here’s a brief update on the development of the Side Story for Her Fall in the Last Days.

Current progress is as follows:

• CGs: 70% complete

• Map design: 30% complete

• Story content: 20% complete

In this side story, the protagonist’s neighbor Rinko and the other man will also appear at the end. So there's still a lot to polish and wrap up.

That said, since this side episode is relatively small in scale, I believe I’ll be able to finish and release it by November.

Thank you all so much for your continued support.
Your encouragement means the world to me!

-----------------------------------------------------------------------------

Previously, I mentioned that I would send CG previews to supporters even if they canceled their subscription.
Unfortunately, I didn’t realize that Patreon does not allow sending images via direct message, and I apologize for the oversight.

To make up for that, I’ve unlocked all the preview images, so anyone who supported me before can now view them freely.
Additionally, I’ve sent the Demo 0.2 download link via private message to all former supporters, so please check your inbox!

Thank you so much for your continued support!

----------------------

This uploaded file is a mosaic-free version specifically prepared for Ci-en users.
For Patreon users, the download link already contains the uncensored version, so there's no need to download this file again.

If you're a Ci-en user, please follow these steps:

• Open the game folder and go to:
  www/img/picture

• From the downloaded file, locate the folder named picture.

• Replace the existing www/img/picture folder in your game with the new picture folder from the download.
  (You can choose to overwrite the files when prompted.)

This will apply the mosaic-free CGs in your game.

Dev Log – Preparing Stories

Hello everyone, this is LactoQuest.

It’s time once again for a development update.

Since the last post, I have to admit that overall progress has been a bit stagnant. This past week, I’ve been focused mainly on foundational tasks—preparing new character busts, pixel sprites, some pixel animations, and various base assets. Although the game itself hasn’t moved forward much, I’m still confident that I’ll be able to push out an update by the end of this month.

Seeing how many of you are excited about the new project truly makes me happy. I also understand that many of you are curious about the game’s details, so in this post, I’d like to talk more about the overall structure of the game, and answer some of the questions I’ve received since the last update.

-----------------------------------------------------

About the Game Structure

As for the story, I’d prefer not to reveal too much just yet. But I’d like to share some insight into the game’s system and design.

If you remember the map I posted earlier, the full game follows a journey from Dawnreach to the royal capital. The content shown in the demo—daily life in the starting village—makes up less than 10% of the full gam

While the ultimate goal is reaching the capital, the player will be free to choose the route. I call this structure a modular narrative system: you might take the forest path to the east or the desert path to the south—each direction leading to entirely different stories and events.

At one point, I considered creating multiple endings and unpredictable story branches depending on player choices. But after reconsidering, I realized the workload and production complexity would grow exponentially. So I’ve simplified and trimmed those plans for now.

Regarding the “trilogy” I previously mentioned—it doesn’t mean the escape to the capital will be told across three games. Instead, each game will feature a new set of protagonists and tell a complete story. It’s an ambitious goal, but I want each title to stand on its own.

That’s why, even with this first title, preparation has been quite extensive. There are 12 characters planned, each with multiple outfits (such as armor and casual versions). Designing and preparing these busts and related assets alone has taken considerable time.

You’ll find new character art previews at the end of this post.

Although the workload sounds heavy, everything is still within control—so please don’t worry. I’m fully committed to development. However, the original goal of releasing in September is no longer realistic. The new target for the full version is December 2025.

This game was originally meant to be a small-scale project, but your overwhelming support and interest inspired me to expand the scope—adding more CGs, events, and story branches. Naturally, this also requires more development time.

The plan is to release the fully updated prologue demo in July, along with the DLsite preview page. I hope you’ll check it out when the time comes!

-----------------------------------------------------

About Her Fall in the Last Days

I know many of you are also interested in updates on Her Fall in the Last Days, both the main game and the side content.

While I was waiting for some art assets for the new project, I took the opportunity to work a bit on the script for the side episode of Her Fall in the Last Days. I’ve been planning to create a short bonus story—about one hour of gameplay—exclusively for supporters. It focuses on Miharu, the protagonist, and Inoshita, and follows their journey after escaping the safety zone.

However, since most of my energy is currently devoted to the new game, progress on the side story has been very slow, and I can’t promise a release date yet. That said, please rest assured—I haven’t given up on it. I’ve been pushing it forward little by little whenever I find time.

That being said, it hasn’t been an easy process. I’ve realized I’m not someone who can emotionally commit to two different game worlds at once. While developing the new project, I’ve become quite immersed in its characters and tone. So when I switch back to writing Her Fall in the Last Days, I catch myself unintentionally writing in the light, cutesy tone of the new game—which doesn’t fit the atmosphere of Her Fall at all. Because of that, I’ll most likely return to that world only after the current project reaches a major milestone.

As for the DLC and Neighbor Route for Her Fall in the Last Days, I plan to begin working on those once the current title is completed. Thank you so much for your continued patience and support.

-----------------------------------------------------

Answering Questions

Q1. How many NTR characters are there? Will there be group scenes?

A: Excluding characters from future entries in the series, this game features 4–5 NTR characters. At this time, group H-scenes are not planned. I understand many players were hoping for modular combinations—unlocking hidden CGs or branching outcomes by selecting different paths—but due to the scale of this project, those systems had to be trimmed down. I’m hoping to explore that type of structure in future titles.

Q2. Are there animated CGs? Why not use Live2D?

A: Like in the previous game, some CGs will feature motion or silhouette-style animation. Full Live2D implementation isn’t currently feasible due to both time and cost limitations. I’m still refining my skills and tools, and I do hope to get closer to that goal in future projects.

Q3. Are there marriage or pregnancy elements in the game?

A: No, not in this title. Those elements are currently only planned for the Neighbor Route in Her Fall in the Last Days.

Q4. Will the heroine have multiple outfits? Is there any content from her perspective?

A: Yes, the heroine will have multiple outfits. The main story is told from the male protagonist’s perspective, but scenes from the heroine’s point of view will appear in the recollection room. For future games, I may explore fully playable female POV depending on audience feedback.

Q5. Are the Pure Love and Corruption routes mutually exclusive? Can they be explored in parallel?

A: Much like in the previous game, key items (such as antibiotics or the mask) will influence which path you end up on. The player must observe, interpret, and make decisions accordingly. Once a critical choice is made, the route is locked in and cannot be reversed.

Q6. In the Pure Love route, is it possible to have H-scenes before any corruption? Can the male protagonist be the first to sleep with the heroine?

A: Yes. If the player makes the right choices, exclusive Pure Love scenes between the protagonist and the heroine will be unlocked. In one of the good endings, the male protagonist can take the heroine’s virginity.

Q7. Does the game have any combat or battle systems?

A: No. There are currently no combat elements in this title.

Q8. When will Her Fall in the Last Days be released on Steam? What about the DLC, Neighbor Route, or mobile version?

A: I’m currently working on integrating three language versions and fixing critical bugs for Her Fall in the Last Days. Once that’s done, the game will be released on both Steam and mobile platforms.

The DLC and Neighbor Route will begin development after the current project is finished.

The new title is also planned for release on Steam and mobile.

-----------------------------------------------------

Final Notes & Thanks

To close, I'd like to share a small update with you.

I'll be traveling to Japan in early June, mainly to handle some tax-related paperwork, meet with old friends, and push forward a few upcoming collaboration plans. It's also a chance for me to take a short break and recharge a little.

Because of that, I might not be able to devote my full attention to game development for a short while. I hope you’ll understand.

That said, I’ll do my best to ensure the development stays on track, and my personal schedule won’t affect major progress. Still, plans can always shift unexpectedly, so if next month’s update or in-game content appears slower than usual, I hope you’ll be patient with me.

Also, all paid content and preview CG will be updated both in this post and the previous one, so subscribing to either one will give you access to everything — no need to subscribe twice.

And just a reminder: once the preview page goes live in July, the demo will be available completely for free. So if you’re only interested in checking out the demo, you can simply wait until then to enjoy it.

Thank you again for all your support and understanding.

It’s your encouragement and enthusiasm that keep me moving forward.

This post ended up being a bit long — thank you for sticking with me to the end.

See you next time!

— LactoQuest

Here’s a quick look at some of the upcoming characters:

🐉 Dragon Hero
Age 25. Known as the “Hero of Heroes.”
Strong, composed, and the true leader of the team.
Yet in unseen corners of fate, he’s slowly being consumed.

🪓 Axe Hero
A brawny powerhouse with the vibe of a friendly big brother.
But beneath that cheerful exterior lies something hidden.
His “relationship” with a certain teammate might not be as simple as it seems.

🗡 Female Adventurer
A beautiful and capable warrior who always wears a smile.
She’s the emotional support of the group.
But the choice she makes… tears everything apart.

Nightbound Courier + Demo in Early May

Hello everyone, this is Lactose Quest.
How have you all been lately?

Development of Stigma of Corruption: Nightbound Courier is progressing smoothly.
Im currently deep into testing and translation work, and over the past week, I've managed to fix several long-standing issues.
Ive also made adjustments to various in-game events to improve their overall presentation and flow.

Compared to my previous work, this game moves at a slower pace, with greater focus on build-up and detailed storytelling.
Especially during event scenes, everything progresses step by step.
At first, I found this style a bit challenging to adjust to, but it's nothing insurmountable!

As for the game itself:
Playing as a novice courier in Dawnreach, the protagonist is not only tasked with delivering letters, but can also engage in various preparations.
The more thorough your preparations before the impending disaster, the easier your journey will become later on.

This game features a pure love route and continues the concept from my previous work:

Avoiding NTR events by making the right choices before they happen

Additionally, discovering and interrupting NTR events before they fully unfold

To protect your childhood friend, you must not only raise her affection, but also anticipate the development of events, make critical decisions at key moments, and sometimes even intervene directly to foil the villains’ plans.

Players will also need to complete certain puzzles to uncover a secret route, allowing faster and more efficient progression.
While it may sound complicated, as long as you pay attention to the heroine’s situation, achieving this is absolutely within reach.

also note:
This game does NOT feature multi-partner (multi-P) events or gameplay.
While multiple antagonists' events may coexist, they develop independently and do not interact with each other.
Those preferring a pure and straightforward experience can enjoy with peace of mind.

The demo is expected to offer around 40 minutes of gameplay, featuring two antagonists, each with two event scenes.
Currently, the total script has already surpassed 20,000 characters, so translation will take a bit more time.

The game will also include heroine state illustrations and various status effects (including a special corruption mark design).
Due to the need for additional adjustments to these visuals and the size of the script, the demo is scheduled for release in early May.

Thank you all once again for your continued support!
I'll keep working hard to deliver a great experience!

You can not only observe ongoing events from a special perspective,
but also intervene to interrupt their progression.

As a courier, you won't just be delivering letters in your daily tasks—you'll also need to gather various supplies.
Helping the heroine, who works as a herbalist, by collecting herbs could be a smart choice.

I’ve also launched a new 3.99 $ support tier,
where I’ve shared some in-game CGs and a freshly completed side story CG.
You're very welcome to subscribe and support me!

That said, I’ll also be posting them in my Discord channel a little later,
so it’s perfectly fine if you don’t subscribe. :)

[Progress Report ] Stigma of Corruption: Nightbound Courier 85%

Hello everyone! This is LactoQuest.
How have you all been lately?

A few days ago, I came down with a pretty serious illness that left me feeling extremely weak—but I’m happy to report that I’ve fully recovered as of yesterday.
Despite how rough it was, I didn’t let it interfere with development. Things have continued steadily, and I’m really excited to share this update with you all.

Since the last post, the development of 「Stigma of Corruption: Nightbound Courier 」 has moved along at a very fast pace.
As of now, the demo is about 85% complete, and all that remains is testing and translation. The estimated playtime will be around 30 minutes to 1 hour.

The demo currently includes:

• 4 CG scenes

• 2 mini-CGs

• And two NTR-type male characters making their appearance

In addition to scripting and programming, I’ve also been helping out here and there with some art support.
Even though I’m not the main CG artist, I’ve been actively involved in bringing this project together from multiple angles.

As for the release:
In the last update, I mentioned that the demo might be distributed through a subscription model. However, after some careful thought, I’ve decided to make it completely free.
It’s not a large amount of content, but I hope it gives you a clear sense of the tone and direction of the full game.
Above all, it’s my small way of saying thank you for all your continued support and patience.

Now, about my previous work, 「Her Fall in the Last Days」:
I haven’t forgotten about the bug fixes! As of yesterday, I believe I’ve addressed all the major reported issues—unless something new pops up.

That includes:

• The sewer event bug

• Memory room events not playing properly

I want to sincerely apologize for how long it took to fix these.
There are still some minor bugs, such as incorrect bust image displays, but I plan to hold off on further fixes for now.
Why? Because I’m preparing for the Steam and mobile releases, along with a three-language merged version (JP/EN/CN) and a future DLC update.
Fixing each build one by one has proven to be time-consuming and error-prone—one fix often causes another issue. So instead, I’ll be doing a full optimization pass once all versions are combined.

Until then, please feel free to continue sending me bug reports! I’ll be logging and keeping track of everything for the next big update.
「Her Fall in the Last Days」 isn’t over yet—the story continues!

The CG-related section for 「Stigma of Corruption: Nightbound Courier 」 is at the end of this article:

• Draft of a CG currently in progress

• 

• Newly designed logo

• 

• A key character (a dragon!) who doesn't appear in the demo, but plays an important role

• 

• And... a new busty neighbor illustration for the side story—drawn especially for those of you who enjoy that kind of thing

• 

Thanks again for reading, and I’ll see you in the next update.
I’ll keep doing my best!

--------------------------------------------------------------------------------------------

There’s something I’d like to share here on Patreon—something I honestly didn’t plan to announce this early.

To be honest, I’ve always felt a mix of gratitude and guilt toward those of you who’ve continued to support me month after month. I constantly find myself thinking, “I should be doing more to give back.”

So, I’ve decided to create something small but meaningful in my spare time: a short side episode for 「Her Fall in the Last Days」.
It’s a new chapter that takes place after the characters escape the Safe Zone, during their journey toward the new city.
The estimated playtime will be about 1 hour, with 5 to 6 CG scenes planned.

This side story is something I want to dedicate specifically to those who’ve stayed with me until now.
It won’t be huge, but it’s a personal thank-you from me to you.

That said, even with the plan in place and the content being relatively small, my schedule lately has been absolutely packed.
I’ll be developing it slowly, piece by piece, whenever I can find time—so there’s no release date yet.

Please understand that I’m not saying this to encourage people to keep subscribing month after month. That’s not my goal.
This is simply my way of expressing appreciation to those who already have.

Sometimes I do feel the pressure. But at the same time, I’m incredibly thankful.
Truly—thank you for being here with me.

Thank you so much to everyone who has been continuously subscribed, as well as those who pre-ordered the project early. I’ll share more details in the upcoming post introducing the new work.

Also, the game is currently on sale — and this is the last discount of the year, so don’t miss your chance!
Thank you all so much for your continued support.

Due to my recent health issues, this update doesn’t add a huge amount of new content,
but I’ve made a major overhaul of the game systems and fixed many bugs.
Here are the full details:

Fixes & Adjustments
Fixed numerous text errors

Fixed a bug where the elevator recollection wouldn’t trigger properly

Fixed an issue where the heroine would disappear unexpectedly

Fixed the convenience store event not ending properly

Fixed the injury event triggering even when the player had antibiotics

Fixed the warehouse recollection being inaccessible even after unlocking

Removed all death mechanics

Losing battles will now trigger unique dialogue and variables instead of a game over

Hunger no longer causes death, but now applies severe debuffs instead

New Content
Casino map and a new ending map have been added

3 new mini-games in the casino

8 new events, including:

Remake of the second pure love event

Casino-related events

A small poster event

Two new endings

Technology District staircase event

A new "invisible wall" event

Complete redraw of the corruption ending

Minor redraws of 4 CG sets

New elevator shadow animation added

All shadow events now include in-between animation frames

New bunny girl poster added

New phone gallery feature added

Many short voice lines added for the heroine

A new idle event (no CG) will occur when the heroine’s lewdness is high

About the Phone Call System
I prepared 32 sets of voice lines for a planned phone call feature,
but implementing it requires major changes to global variables and the core system.
For now, I’ve decided to save this feature for a future title.

New Project – Modular Story R18 RPG: Choose the Fate of the Salamir Continent!

Before diving into the details of this new project, I would like to introduce the lead illustrator for our upcoming series—Mao!

Mao is a highly experienced artist whose expertise has greatly compensated for my shortcomings in illustration, significantly enhancing the visual quality of our works. Starting with this game, Mao will be taking charge of the art direction, while I will provide support along the way.

New Project – Stigma of Corruption: Nightbound Courier

Hello, everyone! Over the past months, we’ve been working diligently on a brand-new R18 RPG—a journey filled with adventure, choices, and desires. Today, I am excited to introduce this game’s world setting, characters, gameplay features, and current development progress!

Story Background: The Turmoil of Salamir

The protagonist is a novice courier with dreams of traveling the world. He lives in the peaceful Dawnreach Village, where his journey begins.

One day, a group of heroes arrives, shattering the village’s tranquility. They have come to eliminate the remnants of a past war, but their mission ends in disastrous failure. The entire hero party is wiped out, the village is destroyed, and an unknown threat looms over humanity.

With the last of his strength, one of the dying heroes entrusts a crucial secret to the protagonist, urging him to deliver this information to the royal capital. Accompanying him is his childhood friend, but the journey ahead is fraught with schemes and desires. What fate awaits them?

Gameplay Features: Modular Storytelling

This game features a modular narrative system, where each chapter’s choices significantly impact the subsequent developments. Your decisions will shape the protagonist’s and his childhood friend’s fate, leading to divergent story paths and multiple endings.

🔹 Open-Ended Journey – Multiple routes lead to the royal capital, each offering unique events and challenges.
🔹 Branching Storylines – At least three main routes, with overlapping chapters depending on your choices.
🔹 Pure Love vs. Corruption – Meeting certain conditions allows for a pure love route, leading directly to the capital. Otherwise, the journey becomes more perilous, filled with temptations and dangers.
🔹 Multiple Endings – The protagonist and his childhood friend’s fate is entirely in your hands. Your choices will shape vastly different outcomes.

Map & World Overview

The game’s story unfolds across several key locations:

🏡 Dawnreach Village – The protagonist and his childhood friend’s hometown, the starting point of their journey.
🏰 Royal Capital – The heart of human civilization and the final destination of the protagonist.
🕸️ Villages Along the Way – The protagonist can seek help from different settlements, though hidden dangers lurk within.

📜 The map of Salamir has been completed! What do you think? Let us know in the comments!

Development Progress

🎮 Storyline and system framework are mostly completed. CG production is progressing alongside development, with an estimated 35 CGs planned.

⏳ Estimated Release Schedule

• Mid-April: Demo release for premium supporters.

• September: Full release target (we’ll do our best!).

Character Introduction (Partial)

🔹 Childhood Friend (Heroine)

• Role: Daughter of an apothecary, protagonist’s childhood friend

• Personality: Kind and pure-hearted, yet strong-willed

• Fate: Her beauty attracts the desires of many throughout their journey… The player’s choices will determine her ultimate destiny.

  

🔹 Female Adventurer

• Role: A warrior in the hero’s party, once engaged to the Dragon Hero

• Fate: She faces a cruel fate as she is dragged into the hardships of their journey.

  

🔹 Merchant
A wandering merchant residing in the village. No one knows where he came from, but he possesses deep knowledge of maps and the best routes to take.
However, his gaze is always unsettling, persistently fixated on the protagonist’s childhood friend…

🔹 Blacksmith
The village’s blacksmith, a man with a muscular build who appears dependable.
He always acts friendly, but beneath that facade, dark desires swirl within him…

🔹 Female Knight

• Role: A knight guarding the royal capital, playing a key role in the story

  

Design Poll!

Version 1.2 Update and Expansion Content Development Progress

Hello everyone, this is LactoseQuest!
Today, I’m bringing you the Version 1.2 update details and progress report on the expansion content.
(Originally planned as Version 1.5, but renamed to 1.2 due to the absence of new content.)

If you have unsubscribed, feel free to contact me, and I will send it to you directly.

I sincerely apologize for the long delay, which was mainly due to waiting for the completion of the Japanese translation. Unfortunately, I still haven’t been able to reach the Japanese translator, so for now, I’m releasing the Chinese and English patch first.

🛠 Version 1.2 Update Notes

First and foremost, Version 1.2 does not include new content.
Here are the reasons:

• There are differences between the version I’m working on and the translation proofreading version.

• New content requires additional testing to ensure quality.

While some CG redrawing and new event production have been completed, I’ve decided to include them in the March update instead.
Apologies for any inconvenience this may cause! 🙏

🐛 Version 1.2 Bug Fixes

• Fixed an issue where some NPCs in the safe zone wouldn’t appear under certain conditions.

• Fixed a bug preventing players from returning to the safe zone from the commercial district.

• Added missing character portraits in certain dialogues.

• Fixed a tile error near the junkyard entrance that caused abnormal event triggers when heading to the slums.

• Resolved an issue where no reward was given after completing Convenience Store Event 1.

• Fixed some repetitive dialogues and events.

• Added clearer indicators for certain hints and events.

• Fixed a missing switch that prevented viewing the warehouse event in the recollection room.

• Fully reworked the English and Japanese translations.
  (Please note that some minor plugin-related translation issues may remain. I’ll conduct a comprehensive review to ensure a smooth gameplay experience.)

• Corrected some text errors in the Chinese version.

📢 Expansion Content Progress

The expansion content is steadily progressing, with the following already completed:
✅ Slight redrawing of 4 CG sets
✅ Added bar bunny girl poster
✅ Added bar harassment event
✅ Added extra insertion variations to the sewer event
✅ Fully redrew BAD END CGs
✅ Improved the phone’s functionality for added convenience

Other content is also under active development.
✨ The expansion content is scheduled for a unified release in late March!

🌟 About the New Project

I’ve officially started working on a new project!
However, since I’m currently focusing on the expansion content for the current game, character illustrations for the new project will be handled by another artist, with me providing guidance and supervision.

🔔 New Project Details

More information will be revealed in the March development log, covering:

• World setting

• Background story

• Main character introductions

• Gameplay and system design

The new project will still be an NTR-themed RPG, but with some changes to the system.
I plan to implement modular storytelling, allowing for more flexible and diverse narratives.

🎉 Thank you to all players for your support and patience!

I’ll continue working hard to deliver even better content.
Please look forward to what’s coming next! 💪

Game Expansion Content Development Update

Here’s an update on future development plans—thank you all for your support!

Important Reminder

If you are still subscribed, please make sure to cancel your subscription ! I’ve noticed that some people haven’t canceled yet, so please double-check to avoid unnecessary charges. This is very important!

In the future, I plan to introduce a $5–$10 support tier, which will include early CG previews and other exclusive content for those who wish to support my work. However, all upcoming updates and DLC for the current game will remain completely free—I truly appreciate everyone’s support!

🔹 Version 1.5 Update (Expected Mid-February)

• Proofread and refine all text to improve translation quality.

• Fix all known bugs and enhance game stability.

🔹 Version 2.0 & DLC (Expected March or Later)

The DLC is currently in development, but since it involves system restructuring, the workload is quite large. Therefore, it will take more time to optimize and polish. This update will introduce new features and improvements, including but not limited to:

• New bar NPC harassment event, adding more interactive details and making the story more immersive.

• Additional bunny girl posters, enhancing the environment and overall atmosphere.

• Revamped hunger/combat-related death mechanics, so instead of an instant game over, certain deaths will trigger extra CGs, endings, or status changes for a deeper gameplay experience.

• A new in-game mobile app, expanding features and offering more interaction options.

• Redrawn CGs, improving visual quality and refining illustrations that were not entirely satisfying.

• More extra events and CGs, adding further content to the game.

More details will be announced closer to release, and the DLC will be completely free!

Please keep in mind that this DLC is meant as a thank-you to everyone who has supported me—it is not a full-fledged expansion. Since I only have about a month to work on it, I can’t add a huge amount of content or make drastic changes. Instead, the focus is on implementing player feedback and enhancing the overall experience.

Once again, thank you for your support<3

Thank You for Your Support

Hello, everyone! Time has been incredibly tight, and I was making updates right up until the last moment. I’m aware that the game currently has many issues and bugs that I couldn’t fix in time due to the limited amount of time I had. However, from now on, I will be continually working on updates and improvements.

Please give me a bit of time and actively provide feedback through Discord, Patreon, or Cien. I will carefully record all issues and optimize the game accordingly.

From the release of the first demo in October to now, I’ve had only three months to complete the game. If I had more time, it could have been even better. Nonetheless, I sincerely thank you for your support! Your support is my greatest motivation.

If the sales perform well, my goal this year is to complete and release two new projects, which will be an exciting new challenge for me. Additionally, all translations in the game were done by myself, and I will be releasing an updated version of the text later today.

Thank you once again for your support!

See you on Discord!https://discord.gg/uPNJTBAp

The game will be published here soon

Hello, everyone!

Due to the suspension of my Patreon account earlier, I only recently appealed and had it reinstated this month. I sincerely apologize for my previous oversight. The game will be launched here as soon as possible. For now, I only plan to use this platform as an additional way to sell the game. Please remember to cancel your subscription after purchase. I deeply appreciate everyone’s support and will continue working hard to deliver better projects. I will be launching it on the 15th.

Below is an introduction to the game.

Game Introduction

Two weeks after the outbreak of the zombie crisis, a quarantine safe zone was established. Together with the heroine, you must find a way to survive. In this life-threatening situation, can you protect the one you love?

Within the safe zone, there are no laws or moral boundaries. Your neighbor has his eyes on your wife, and his actions are cunning and secretive. By the time you notice something is wrong, it may already be too late. The game provides multiple perspectives, including the player, the heroine, and the rival. Perhaps you can protect your wife with intelligence and strategy; if not, you will at least uncover how she fell.

Game Features

• Free Action
  After the crisis begins, you are given a limited exploration cycle. Each day is divided into three periods: morning, evening, and late night. You can freely decide how to allocate your and your wife’s actions. For example, one morning, you might leave to explore alone to save resources, only to return home and hear strange noises coming from the bedroom...

• Restricted Vision
  Whether outside in the dangerous quarantine zone or inside the "safe" confines of your home, your vision is always limited. For instance, when the bedroom door is closed, you cannot see what’s happening inside from the living room. Perhaps you can find other ways to uncover the truth...

• Phone Functionality
  Fortunately, your phone retains basic communication capabilities within the quarantine zone. At critical moments, your wife may call or send messages to ease your doubts—or deepen them.

• Atmosphere
  The game is set against a backdrop of intense and oppressive danger, with a multi-perspective narrative that creates a deeply immersive experience. Every decision you make will impact your wife’s fate and determine your shared future. In this world without rules, only your intelligence and strategy can protect your love and dignity.

• Emphasis on Strategy
  The key to protecting your wife lies in carefully planning your exploration and resource usage rather than trying to fix things after the crisis fully unfolds.

Before the outbreak spiraled out of control, you and your wife were fortunate enough to stockpile some resources, allowing you to survive the first two weeks without venturing outside. Even luckier, your apartment building is surrounded by a quarantine zone housing nearly a hundred survivors. But how long can this fragile stability last?

To survive, you must take on dangerous tasks, and through exploration, you may uncover the truth behind the crisis. Each day is divided into three periods: morning, evening, and late night, giving you the freedom to plan your actions. You can choose to explore alone or bring your wife along, though doing so may consume more resources.
