When the challenging level is 10 of the exact same thing, asteroids that get faster and faster and block almost the entire width of the screen and offers just a very few asteroids that may be hiding additional bullets or shields, that is a sign of a game that should be uninstalled and then you look for a better quality game. The graphics are awful and not up to par with similar games. Also, too many ads for no reason. Skip this one. Trust me. Skip this game.
