I wanted to do some more packs set at night.
The problem with night maps is the visibility - while everything is dark, it's hard to get this cool points of focus on the map. Adding some bright elements makes the map more interesting - so I stated to tinker on what was supposed to be some sort of fluorescent micro organisms or possibly jellyfish type of creature making the water bright and vibrant at night, end this is what I ended up with.
I need to fix some things up, but I'll be releasing full version soon. Stay tuned!
