I was thinking how it’s pretty easy to fatten anybody up and I think I remember reading about a harder difficulty? But my idea is adding a new toggle called activity that could be a sort of passive weight loss system for every character for example (Sporty 2x, Active 1.5x, Average 1x, Lazy 0.5x, Couch Potato 0x) this could also tie in maybe to the corruption system I saw you talking about. I know it’ll be awhile but can’t wait for more!
I'd definitely like to add a system where girls try to lose weight in the background. It'll probably be part of the difficulty system as a feature that comes into play at standard difficulty or higher (with the current game being easy mode).
I'll include your suggestion that different personalities are more driven than others & that it be tied in with the corruption system!
