Simple game, attack each-other using miniature versions of yourself. Player 1 (Blue): Move: Side arrows. Jump: Up arrow, Shoot: Down arrow. Player 2 (Red): Move: A and D keys. Jump: W key. Shoot: S key. The heart that spawns will regain 1 health bar.
If this project gets to 50 loves, I'll remake it where you can choose your own special ability and attack mode! Have fun Fighting!
