Eat the Dungeon features very heavy weight gain where you can be heavily slow down by your weight, though it can be removed by upgrading. The adventurers (all of them are female) are at significant weight levels but not immobile yet, though with in two major updates the third set of weight gain portraits will be featuring immobility in them (though they still can do things).
Best part you can decide how fat/heavy they can be, though they go back to being normal when you extract the weight from them.
The best part is, Bewildered Angel is currently updating it; they’re on here, now, though that’s probably not news to you if you’re keeping up to date regularly. This is mostly for anyone not in the know.
Fattfatt Game made by j8867bbw. Cool artist too. Fatteningis other game made by they, for halloween, multi-ending.
They have other games, but they don’t fit quite well the criteria of getting immobile/blob except if you wait until the final of the game.
That’s kinda rough to say. I mean, I used to be the same, but saying you’re looking for better is a bit rude to the artist. I think the Knight retains her ‘figure’ as of the most recent update, if you want to play at all, but it’d require levelling the Warrior and the Thief (I’m not a big fan of the way they end up, personally, but I can’t say I hate the way the Bard and the Priestess look at the end of their current growths!)
I think they also did Pkniad’s Prison, right? There are a couple of endings in that where she gets huge (in the best way)-one of which being just to go back into the first room (oops, sorry if that’s a spoiler >_>)
