Arrow keys to move, space to fire at the asteroids , you DON'T have to dodge the stars (white things) and there are some power-ups! Here are what they do: the Venusian (the orange one) makes you fire three lasers; the Luna (the turquoise one) makes a shield around you; the Martian (the red one) makes your lasers fly faster; the Jovian (the pink one) makes you dodge faster; the Saturnian (the yellow one) slows everything down; the Uranian (the green one) makes you smaller; the Neptunian (the blue one) freezes everything; and last, and DEFINITELY not least, the Plutonian (the purple one) does the same as the Luna, the Martian (but more effective) and the Jovian.
