Sanatorium - Version 1.67 3D horror game. You must collect 8 pages while avoiding the Slender Man. Staring at the Slenderman will drain your sanity - empty your sanity and you will be caught. Sprinting will decrease your maximum stamina, so sprint only when required. Beat the game and you will get a nice suprise. 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! Try to win, do not fall into the hands of the Slender Man!
