In Space Smilies you have to destroy the hordes of advancing smilies (and various other shapes) by shooting everything that moves. An old-school shmup (i.e. shoot’em up) game that gives you a better feeling playing on a phone/tablet than you’d have by playing the classic version on an emulator. Just as the classic version, the invading ships drop bullets and destroy you, from time to time an UFO "comes by" to drop some bombs right on you and finally there’s also kamikaze ships that sacrifice while trying to destroy you.
