WASD to control Blue Player Arrow keys to control Red Player S or Down key to shoot a spell. You can jump on the orbs. Every few seconds, an orb appears and drops. If you touch it, than you will get a power (a hat is a speed boost, a heart is health healed, lightning deals damage and nothing means your shooting speed is increased). The are 3 stages, Purple City, Jungle, and Music Place (idk). That's it for maybe forever (I'm too lazy).
(For a school project) Thanks to @alphabetica for the laser sound Everything else is by me (even the health bar, I'm pretty proud of that.) Please comment what you think I should add (game-play improvements, new features, etc.)
