Use the arrow keys to move, x to shoot, and z to shield. Avoid the falling bits, or shoot them to get extra points. You must collect the Power-Ups to increase your energy, which is required to use the shield. If you already have max energy, it will give you health back. Post your high-scores in the comments!
