sorry if im late to this comment, but this game is nice tbh!
Here's my fan made endings while the game is in W.I.P and A Demo!
Healthy ending: Kept her healthy as she is since you first met her!
Big ending: Ever since you fed her at the start, she gained alot of weight and fat. put all the blame on you!
Normal ending: Probably kept her weight the same but a bit fatter than usual.
