An interesting note about this level is that after completing the level and going to the teleporter, you have two options; to go to the final level, Risk of Rain (Level), or "loop" back through old levels. Looping back will take you at first to the first level, Dried Lake or Desolate Forest, at the current difficulty; after beating that level, you again have the option to go to the final level or loop through to the next level (Sky Meadow or Damp Caverns), and so on.

To the left is the Temple, which is three floors. Health Shrines can be found on this level, as well as potential golden chests. One of the golden chests requires Photon Jetpack to get up to, since it's on a tall ledge that is otherwise inaccessible.
