E - You Cant Escape! R - Erasure Barrage also since you probably wont look much in the notes section I'll put it here, the map has collision. SECRET: use E on the right gate... anime reference.
NOTE: this is abandoned due to me lacking creativity and skill to work with the pen tool, so don't expect much. erasure speed changes based on how far/close you are from the dummy, farther away = slower erasure pull, closer = immediate erasure pull, you can also erase the dummy! wow... what a suprise.
