- Infinite jump
- There is a glitch in the purple gem you can purchase at the market. The purple gem allows you to "change size" in the description, shrinking you down to fit in small areas. However, when using the gem for Sonic you can jump an unlimited amount of times. When you press Jump while holding Activate Ge and repeatedly tap A, your character will act as if he wants to do the homing attack. However, the game will glitch, cancel it out, and allow you to jump as many times as desired while moving in the direction you wish to go. This allows you to get to interesting parts of Soleena or an action stage that you were not meant to access. If you die or find a alternate way to lose the gem, it may be "out of stock" for some time.
