You will find the location of pillars, keys, and eyes that need activated for the various extra content. Planet surface and the maze are not featured. For the maze, refer to any other guide/map. This map is only intended to make it easier to navigate to and find the pillars, keys and eyes.

The key in the grey area is reached by beating the boss on the planet's surface.

The death laser room refers to entrance before the maze.

Not all secrets are shown, but those missing are not important to progress or extra content, and are just Easter eggs.
