The game is almost like missile command but in space and planets. You score increases by shooting the red circles. You score also increases by the size of your total population in the solar system.
If you have less than 500 people in the solar system then it is game over.
Defend your planet(s) so that your population can grow. Move the pointer over to another planet to transfer people to that planet. You can move from planet to planet by holding the pointer over the planet for 5 seconds. You can only move to a planet which is green.
