I really love this idea I have a suggestion just like this with a few more I think i should put it here
I have 4 ideas in total and all of them could be toggled to make the game harder/more erotic or just so you don't see it, you probably wont add any of these because they are hard to code but still thanks for reading if you do and thank you even more if you add one!
1. Could there be any fattening that make the game harder, there is weight classes like the preg except fat comes from overeating or eating unhealthy food or they can combine with your pregnancy and it stays until you sleep, die or exercise and you can ban certain ways to get rid of it like sleeping doesn't get rid of it, so then you have to go die or exercise or ban all ways and you have to go in a new place like the gym once city gets released.
2. Stuff like slime inflation can be permanent it can also make your belly even bigger and same goes for preg and could there be more preg versions like if its a slime your belly squirms inside and can only get it off by showering or you can eat slimes yourself to escape them or not have to deal with them like how you get stuck in the garbage area you can just eat them to get out but you may walk slow unless you toggle slowness off or something.
3. Can there be more character customization like wider shoulders, height, a belly, ear placement, bigger boobs. select coloring (like you click the part or something like that), your digit grade how high your heels go up to and more like that.
4. My last idea would be mimics that can copy things like shelfs or boxes and can only give you small clues to how its not real like its out of place or is moving a little it would be fun to accidentally fall into one.
