Slenderman's Shadow is a horror adventure game based on the indie game Slender. Claustrophobia is the fifth map of the Slenderman's Shadow series. The player is in a massive hedge maze. The goal is to collect 10 keys; 9 are fake, and 1 is real. Getting the real key is the only way to open the door and escape. If the player manages to complete the game, they unlock a mode called "mushroom trip mode". In this mode, the map has been changed into a rainbow coloured world.
