A simple little game that is curiously addictive.
To all those calling this game crap, etc pull your heads out.
This game is a joy to play. Very simple in concept (best described as Space Invaders in reverse) but once you figure out little mini strategies (the game not being really complex enough for a tactic to truely be called a strategy :)) it becomes quite difficult to stop playing.
Simple ideas are often the best, this is proof.
