NULL by Strange Girl, Fouzi - Adult Sex Game

Null is a social deduction game with time travel elements.

You are trapped in a mansion with 8 other people and forced to play a game with some "Werewolf/Mafia" elements except the consequences are very real. But wait, that's not all, every time you die in the game you are sent back to the start of the loop forever trapped in a hellish game with no means to escape.

But fear not, you're not alone. "CC", a strange girl who seems to also retain her memories after each loop, is also seeking an escape.
