i found this page by following the game's deviantart and discord pages, but i usually find kink games on itch by looking through that kink's tag, and i'm sure they help with the recommendation algorithm as well. i've seen the tags expansion, breast-expansion, giantess, weight-gain, and pregnancy used for other games, but i'm not sure if there are tags for butt expansion and fmg used by other games on itch.
