Puzzle Rooms are simply rooms which require the player to utilise their character's skills to solve a certain puzzle in the room. Such puzzles include getting past a series of spikes and/or steam, navigating a series of elevators, guiding Embermites or Watergrubs around the map, or just hitting switches to open the path to the next room. Many puzzle rooms have a Bulbwall or a Plugbulb blocking the most direct path through the room. These can be destroyed after completing the course, allowing the player a faster route when passing through the room again.
