Pay close attention to the lights on the Power Activator – they indicate your enemy's actions in battle:
Purple – enemy is unprotected – time to attack!
Red – enemy was hit
Green – enemy is charging up their attack and can't take damage – get ready to dodge, hide, or raise your shield!
White – enemy is attacking
Blue – enemy is shielded – use your Palm Cannon!
Flashing Yellow – Activator is about to explode – time to hide behind something big or run from the room!
