This game is actually a 2 player game if you use controllers (turn on controller mode in the browser). Since this is a browser game, it will work on xbox and other gaming systems as well as desktops/laptop computers. However, it's not mobile-friendly yet.
Use the mouse or controller to move your character around and click to fire. The click firing has limited but regenerating ammo. The ship will also auto-fire with infinite ammo.
Shoot or touch the powerups to temporarily upgrade your ship, but don't touch the enemies.
