It is about Bob, a sleepwalker who often ends up far from home and in dangerous locations due to his condition. He only trudges in a straight line and turns when he hits objects, and so player assumes the role of Subob, a goat-sized creature with a human face. His task is to guide Bob back to his bed by picking up Magritte apples and dropping them in his path, so that he would turn at a right moment.
This game has been heavily inspired by surrealist painters such as Dali and M.C. Escher, and so the levels, like one in the screenshot, are frequently filled with various impossible architecture.
Back to Bed provides examples of the following tropes:
- Bizarro World: The world of the game, obviously.
- Bottomless Pits: One of the most common hazard types.
- Bridge Logic: Later on, Subob can bridge gaps by using fish bridges.
- Death Is a Slap on the Wrist: Bob dying just instantly sends him back to the beginning of the level with no interruptions, and so
- Interchangeable Antimatter Key: In the Nightmare mode of the game, Subob needs to ensure that Bobs path will overlap with all of the keys lying around on the level, so that the door to his bedroom will be unlocked at the end.
