A Barrage of Weird Rules Started, and the Female Supporting Character Turned Around and Killed Countless People

Please Recommend Some Weird Rules!

Please recommend some weird rules! There are rules in the game that the protagonist needs to distinguish between true and false, and the protagonist will not know the plot just by picking it up. It is best to have a setting in an escape or horror game. I want to see the protagonist grow up and reflect the charm in a touching plot.
