My biggest criticism of your game is that it's not really clear what's going on. It's not clear who a lot of the characters are or why they do the things they do. It's not clear how they know each other, or why they like/dislike the protagonist and each other. It's not clear why the protagonist is in the situation they're in. Things seem to just sort of happen randomly.
I realize you're trying to make this a mystery of sorts, but if you want the player to be engaged you can only have a few things be mysterious at one time. If too many things have question marks over them, the player will assume you don't know what you're doing as a storyteller and start caring less about your story.
Also, I realize castration is your kink, but it isn't clear why so many characters are so fond of it. Like, 3 or 4 dicks got cut in 0.2. Most people would never even think to do that to someone. If it's some cultural quirk of your game world, you should probably explain where that comes from.
Your job as a storyteller is to take someone who lives in this world - the player - and make them understand this other world you created. The more your world differs from the real world, the more you'll have to explain to them. I can tell you've worked hard on the game, and I think it has the potential to be interesting.
Anyhow, I thought the scene where Scarlet fucks Charlotte was pretty hot (until Scarlet got her dick stabbed... again.) Hopefully she'll get another chance to fuck him (and actually finish this time.)
