Choose your spaceship using the arrows that appear right next to it. Move your mouse around to control your ship. (I recommend ship number six) Click to shoot. Space to use your laser beam. (if you already used it wait for it to recharge) Game modes: Baby: insta-hit meteors. Normal: well, normal. HARD: shooting stars, double meteor health. Power-ups appear every 30 - 60 seconds, shoot at them to use them! If you hit an asteroid you lose integrity. (note that the asteroid's debris can also damage your integrity) The objective is to destroy as many asteroids (and ships) as possible without getting destroyed.
