Cosigning livegoeson4 (especially Some Bullshit, which is the best-written comedic RPG on the site) and adding:
The Gloucester Estate Spooktacular: a short, multi-ending twine game about attending a Halloween party in college. With efficient and flavorful characterization throughout, it feels genuine and sweet
– Witch of Gluttony
– Olive And The Ruby Bra
Depending on your taste for the style, these both do a fine job with certain anime/jrpg personality archetypes. Note that neither are finished quite yet
Avril’s Appetite If you like meta moves (writing and gameplay) and bratty characters, lachevite is the creator for you
Insatiable Hearts [v0.1.2D] - A monsterfucker+Weight gain Twine Game: As a work-in-progress, this one is light on finished character arcs, but has flavorful NPCs in spades. Twine adventure game built on wandering a strange, dreamlike world
On my Watch list: Myre’s Massive Mealtime - a stuffing game (v0.37 now with android), a game about a first date between two characters who are into this, but don’t know how to approach the subject
(And I can see you’ve tagged this as bbw and female, but in case any bhm/male fans are reading):
Cards of Gluttony - a gay, weight gain card game [v0.3 released on 25/10/2023!] Deck-building game with an on-going story and a growing (heh) NPC roster, from the gruff and sarcastic barber to the himbo baker to the domaneering rival (and more!)
The Curse of Something: A RPG Game About Large Furry Men Twine life-sim/rpg with a perfectly breezy tone. Characters are fun and plentiful.
Enthralled - An interactive story about a hedonistic vampire and his servants Dark horror game about escaping a vampire’s compound after you’ve been hypnotized. If you vibe with the tone, this goes full tilt, with layers of character history and tragedy to find
