The game revolves around navigating a main character named Dude from the third-person perspective about a secret landscape under his bed in search of a lost slipper. The game is in 2D and consists of a number of puzzles centered on using items collected and interacting with the 45 other NPCs. There is no dialogue in the game and the difficulty often derives from trying to determine why a character behaves in the way it does. Solutions to the puzzles are often illogical, in keeping with the atmosphere of the game which has been described as psychedelic.
