Performance

Orbital Assault makes extensive use of javascript and the canvas tag so IE may experience problems. The smaller your window, the better the game will run. You'll most likely have best results in Safari/Webkit, Firefox 3, Opera, and Chrome. If your browser or computer isn't fast enough with javascript or canvas, it may crash your browser.

You

This is you! You are equipped with amazing flying powers, and the ability to crash into the ground, destroying everything in your way.

Healthy the HealthCapsule

Healthy just wants to help you, at the beginning of each new tier he will float on in from the left side. Bump into him and he'll disappear. Smash into him with your attack though, and he'll dispense healing bullets! Also, increases maximum health by 10.

Enemies

This is a tank, they crawl along at the bottom of the screen. They are equipped with artillery cannons and eventually flak cannons.
