At the beginning of the game, you’ll be transported to the legendary dungeon that so many fear. Here you’ll find an endless series of office spaces, the walls of which are covered in faded yellow wallpaper, and the constant hum of lamps. This place itself is unpleasant enough that you’ll want to leave it as soon as possible. You should also remember that the creepy Slenderman dwells within these vast spaces, and he has no intention of letting you leave just like that. This monster is waiting for the right moment to attack you. Try to prevent this and escape Backstage without encountering this bloodthirsty creature. To move around Backstage, press the arrow keys on your keyboard. You can look around using the mouse. Exercise extreme caution when moving around Backstage to avoid encountering the monster.
