The idea is for a weight gain mod for Risk of Rain 2 that adds fattening food items like cake, pie, soda, etc and when you pick up the item your character will gain weight. The max size could also be to fill up the entire stage or at least half. It would also benefit you like giving the characters more health or more defense.
Oh yeah, I had an idea similar to this not too long ago! It was a Lunar Item called “Caloric Cake”. Every stack of it would increase the survivor’s health but also make them fatter and lower move speed. One day I would like to learn C# programming language and 3D modeling to see if I couldn’t implement something like that in the game.
