The first point Is kinda self explanatory you have confirmed that we will be able to acquire party members at some point I think it would be fun if they could also gain weight, this would also allow them to have different body types and opinions on fat, depending of course on how much personality you want to give them.
My second suggestion is for a spell caster who can also attack physically. It would probably be limited to weaker spells but would also gain some skills for physical attacking.
Also I feel as though fairys should be nerfed as right now they make it too easy to lose weight…
Anyway best of look with the game and I hope development is going well.
