Meteorite Defence

Space, it's sort of a region from which you do not know what to expect. He is very big, and it flies just set. And if suddenly what that stone will not fly because we need our land, then she faces a very high risk. But today, humanity has learned through a special laser to manage these meteorites, and now uses them for what would be protected from the aliens. In each level you will need to try to throw large stones in the alien ships before the time, until you do not destroy them. Good luck!
