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 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.
