I've been loving this game. Its my personal favorite of mine of this genre on Itch io. And I have a couple ideas that might be cool.
I'd love to be able to hang out with/go out with multiple girls simultaneously in the future. I think interactions between the girls could be cool. Like getting tag-teamed by two feeders or tag-teaming a feedee with another feeder. Maybe you could take a feeder to your place to help feed a feedee/blob already living with you. Or vice versa with going to a feeder's home.
Another idea I had was for feeders to also have/gain other girls to feed like the player does. Maybe OnlyFats model/manager could be an occupation that can be given to them during creation? Maybe they could even have a couple girls already living with them? Or they can eventually gain other girls/feedees that they can introduce to the player that they will feed and/or make content alongside the player? Maybe they could already have a blob or two living with them. I recall someone else mentioning using a blob girl as a bed, which I think is a fantastic idea. Having sex with a feeder on top of a blob girl you or they have already fattened up I think is a great idea.
looping back to the OnlyFats model/manager idea. It might be cool to see how that could effect the game/dialog. Maybe a feedee can start off as an already famous OnlyFats model that the player can meet? Or a feeder can start as a wealthy OnlyFats manager? Maybe said OnlyFats manager feeder can pitch OnlyFats modeling to the player instead? Or the player could partner with them? Perhaps a feedee OnlyFats model can eventually introduce the player to their feeder/manager?
I would also love to see a dominant feedee personality. Like the dominant feeder, but instead they demand the player feed them instead.
Anyways, I'm just spit balling ideas that came to my head. Main points are: I would love to see the OnlyFats stuff expanded upon, and possible interactions between girls. Especially feeders.
Btw, sorry for the essay. I just love this game.
