The space-rocket MUST NOT touch the rocks no matter what if that happens, you lose. use the up and down button to move. Press the left arrow key to activate a small but fast green double laser beam and right arrow key for a big but slow red double laser beam. space is for a huge blue orb. these help you destroy the rocks eack rock you destroy gives you 100 points. Good luck!
