You move automatically, but press the up arrow to use boost. Press the left and right arrow keys to turn. Press enter to shoot proton torpedos. The goal of the game is to shoot all of the turrets and the reactor with as many proton torpedos and as much health as you can. Please comment if you get the highscore.

Credit to @MrSupreme2 for the proton torpedo. Credit to (I forget) for the music. I think it was called electrodynamyx.
