On the entry screen press START to begin the game and click the magic bar to change the magic mode (Ice, Fire, poison) press w to walk forwards (press x and w to go super fast but watch your blue stamina bar if it runs out you wont be able to move), press s to walk backwards (The wizard will always walk relative to your mouse-pointer) press space to shoot. Warriors/baddies will come from all sides to attack you in the middle, evade them and eliminate them to win the game (there are 3 waves and one boss wave, they get harder as you progress).
