There may be some problems (draft) so forgive me about them. The rocket moves by following the mouse when pressed. Press the spacebar to fire. Watch out for the alien (it appears when you touch the planet at the bottom right of the game). The alien give one life when it explodes. The rocket loses control after being hit by the asteroids or the alien. To fix the rocket touch the flouting thingy to fix it .
