P1 : B to attack( different directional inputs change the attack and also if you're in the air will do different stuff.) wasd to move and space to jump P2: arrow keys and K to jump L to attack.
Custom 1: Press I to use Triple Homing, a Homing attack where you dash 3 times at the opponent. has good range Custom 2: Press O to use Sonic Flare, you will launch the opponent. good for combo setup this is a VERY old unreleased project
