Here's the key mappings to the game.
My ideas
-red color for the keys that aren't used and he does a breathe affect in white.
-WASD, shift, ctrl, space a rainbow wave
-Rest of the keys reactive with a base white
-Q and 4 turn to light blue, b a light green, the rest of the reactive i'll give you creative control.
Thanks again ^_^
Edit: I forgot to add that 'v' is a melee attack
