BOI have you played the game? xD That Rat's tiddies are the size of my head. I'd be all for character customization but the inflation stuff is wayyyy beyond me and would kill any interest I have in this project.
In Koboldkare I had bloat from eating too much, there were missions that required it. But it was optional after that.You can add inflation by means of some fruit. But it should be optional for the player to consume it or not.Or you have to eat a lot for it to happen.
