Infinite Light Flight
This glitch happens because light shield terminates a combo. To exploit it, Simply use Light Flight, then immediatley Light Shield, Light Flight, Light Shield, etc. You can gain an infinite amount of altitude (height) with this glitch, and go over walls or through some ceilings.
Skip Missions in Hero Mode
You can skip some of the starting missions in hero mode. First, turn on the turbo jetboard secret. Then, use the jetboard to jump from island to island by executing the L1 high jump and a forward flip.
Unlimited/Easy Precursor Orbs
Go to any oracle statue and trade metal head skull gems to start an orb search challenge. Go to the orb and wait for the clock to turn to 00:00. Even though it says 00:00, it takes another second for the time to run out (I.E. 00:00 is really 00:00.100) So wait one more second, and then press Square to dash at the orb as soon as time runs out and the mission failed screen comes up. You will get 3 orbs, and be able to retry!
