Since the gameplay seems similar, maybe you can draw a few inspiration from this Souls of Gluttony 1.1.0 version Released
It’s nice to see some male content around here for ones, the male to female ratio in here is to far apart.
Also ai seems to really struggle to made morbidly obese image, I don’t know how far you wanna take the weight level to, but if you wanna go all the way then you’ll have to partner up with an artist at some point.
Either way it’s a great foundation for a game, hope to see more of this game in the future.
