Gallery Edit


  • The Keystone Monitors are reminiscent to the item boxes in the Sonic the Hedgehog series with similar abilities mentioned, such as Invincibility.
  • When entering to a cutscene with an active shield, the shield surrounds the other playable character instead of main character in the story. When the cutscene ends, the shield returns to main character. This glitch works in Relic Maze. Alternatively, holding a Phantom Block at the end of a stage may cause a phantom block to appear above the shield during a cutscene. This glitch also works in Trap Hideout.
