so yeah, how about some sort of weight gain idle game? there’s a number of different systems and variations out there, so the potential for one or more games is great. here’s a couple i can throw out
the classic: your basic clicker heroes knockoff, where you defeat enemies to gain currency to level heroes. the difference here being that each hero’s portrait chances with each tier, gaining more and more weight up to immobility. example: Clicker Heroes on Steam
the rpg: more akin to some of the newer idle games, where instead of just having clicker elements, you have a whole town to take care of, with each building providing a specific function. you recruit heroes, form them into squads, and send them out to adventure, gain exp/weight, and bring back currency and materials to upgrade and improve your town. example: No-brainer Heroes 挂机吧!勇者 on Steam
the solo: pure rpg, where instead of having a squad, you have a single character facing off against squads of enemies, killing them all to get exp and items. couple of potential features could be multiple characters/portraits, stats increasing weight to various parts (boosting strength could increase butt and things, defence belly, magic breasts, ect). example: Great Hero's Beard on Steam
the harem: …yeah, possibly could just make crush crush but with weight gain elements. example: Crush Crush on Steam
Mio IS best girl imo. Other girls I’d like to see plump: Elle, Bonnibel, Bearverly(her human form, her bear form’s plenty thicc. XD ), Alpha, Pamu, maybe Jelle, Odango, Shibuki, Sirina, and Roxxy.
And from Phone Flings(Besides Wendy): Generica, Lotus, Sawyer, Lake, Willow, Blanche, and the new Babybelle.
…There are a LOT of girls in crush crush(I didn’t even list them all, just my favs. XD). It’s almost reached gacha game levels of roster size.
