Hit The Comet is fun arcade game available on Google Play.
Which this game, you can relax and have great fun I think it's original. Asteroids are moving across the screen (another planet - a different way of moving) and you must destroy mostly all asteroids. To do that, you have to tap one of the asteroids on the screen. Asteroids destroy into 4 smaller asteroids. If small asteroids hit bigger, the bigger again destroy into 4 small, etc..
Game is free
