You move around with WASD and fire a laser by holding down space for as long as you want the laser to last for. When you use your laser, your Power Level goes down. (See it in the top left corner). You can't use your laser after it gets below or at 25. When you're not using your laser, it slowly regenerates to a maximum of 350.
Try to get as many walls destroyed as possible. The more you destroy, the more there are and the laggier your PC gets. Comment your high score in the comments. Mine is 1373. Also, please do not ask why Nyan Cat looks like that (It's from the bird's eye view) and please do not ask why he has a laser gun taped to his back.
