Trippy trails, mirrored levels, and big head mode!
Captain Qwark commercial
Once you've beaten the game, wait for the credits to end to view a commercial featuring Captain Qwark.
Easy Bolts
After getting the metal detector, go back to previous planets and search for hidden Bolts. Not only does the metal detector help you find more, but the planets' items also respawn after you leave it.
Magnetic Wrench
Note: This also works with the Vacuum Gun. Execute a Comet Strike at far away Bolts. If the wrench passes near them, it will attract the Bolts to you. This is especially useful around water or Bolts that are across chasms.
