There's this game that I see constantly on YouTube back then. It was a pixel-like game that fights monsters and enters dungeons which you see an enslaved girl or some sort.
And when you get towards at the end of a dungeon, the girl transforms into a creature that is supposed to be an ancient god of death or something and it has three stages of transformation. I can't remember the game name, but I would love to play it soon.
Sure, nothing wrong with it in concept. It does feel kinda cheap when the character is clearly just a normal person with monster features for the kink, though. On the other hand, being a non-sapient monster makes something not exactly LI material. I think there's a nice, unique way to balance a character's traits such that they clearly come from a non-human background, but remain very much a sapient, consenting adult.
