Click the mouse on the baddies and bullets to fire rockets from your fighter. If the rocket hits a baddy or a bullet you earn ten points. If you destroy all the baddies in a level you go to next level. If a baddy or a bullet hits the earth the health of the earth gets reduced by 10%/5%. If its health becomes 0 the game ends. Updates are available when you reach certain levels.
