Here are some more indie games I found/knew about.
Frogatto & Friends - This one is pretty old and I played its demo(?) back in 2013. Basically, it's a 2D platformer that allows you to swap between playable characters. Frogatto's main ability is his tongue grab which he uses on both enemies and objects. To be specific, Frogatto actually swallows everything he grabs and stores it in his stomach. While he does get notably fat from doing this, he doesn't digest anything he swallows and needs to spit out the thing eventually. I say eventually because, if I remember correctly, he doesn't slow down whenever he swallows something and can still move freely. I still have the game's demo(?) on my external hard drive. I say that it is the demo because I honestly don't remember anymore but I couldn't afford to buy random games back then and I had a thing for playing demos. So, it's probably a demo but I'm going to replay it to be safe.
Eatvolve - The concept for the game is interesting but vore isn't that interesting. The game's primary mechanic is that you kill and eat other creatures to gain their abilities/parts, kinda like Cubivore. For the most part, the vore is just a quick munch off of another creature's corpse. I can't say much more as I've never gotten far in the game due to its random generation. But there is supposed to be an upper area you can get to, somehow.
Mmmonster - This one is a fairly simple puzzle game. You are a red demon looking for children to eat on Halloween and one kid decided to wear a cheeseburger costume. You walk up to him, eat him, and beat the level. It was made in three days so there isn't that much content there.
Frogatto is $10 -
