Spelunky is another 2D platformer with procedurally generated levels [18]. This game uses Rogue-like level generation techniques to fill rooms with passages, treasure, and enemies. Spelunky belongs to a sub-genre of 2D platformers that is not well-suited to our approach of rhythm based level generation, as the challenges in the game are not dexterity-based, but rather exploration-based. Examples of the dexterity-based platformers that we target are Super Mario World [9] or Sonic the Hedgehog [12].
