3D horror game. Find the real key from 10 ones available to open the door in the dark maze while avoiding the Slender Man. Staring at the Slenderman will drain your sanity - losing your sanity will have negative effects and will likely get you killed. Sprinting will decrease your maximum stamina, so sprint only when required. Throughout the world, there is no one who is not afraid of the Sender Man. He has no face, he wears a black suit, and he abducts people. Do not look at him, or he will catch you!
