I guess the most common feedback I received about Parallel Desires was that it wasn't possible to individually choose how each character would be and behave. (If you don't know, in Parallel Desires, you can only choose whether you're going to be top or bottom, so the game can either be completely straight or completely futa on male.)
I decided to use the Christmas project to try to create a system that would make this decision individual for all characters, creating greater variation in the game's scenes 😉😏
If everything works properly, I'll probably use the same system in Parallel Desires in the future 😁
