Hello!
Take a look at my future plan for the game! I had already planned what I would do for the most part, like the ending and route. My game will be divided into two halves, the first and second. The first part will consist of three stages from the adventurer guild for you to finish. In the meantime, your rival will raise the corruption point, and if one of the girls falls, you will be thrown onto John's corruption route on the next part. Unlike the first part, the second part will focus on exploring rather than staying in one location. The second part won't use the invitation party mechanic, it will have a different corruption mechanic based on what route you are on. Only three of the endings will include postgames or afterstories.
For now, that's it! It may change in the future, but more or less, the game will be like that.
Q: Does that mean there will be two games?
A: Nope!
Q: Is it possible that there will be another girl added?
A: I don't really know, honestly. Maybe yes?
Thank you very much for your support!
