Oh woah I didn't know at all that framework, done some research and seems to be a pretty big thing lol. Also loved how it works, maybe I'll get it in the future but for now I want to mess a little with ren'py.
And about Koikatsu I was thinking of that, found it on a reddit post and I could see the similarities, got the modded one that everyone uses.
Ty a lot buddy for helping me out with the questions!
