"There were many mimicries of the classic-Geometry-Wars-action iDevice gamers longed for, spanning from Isotope, Nano Fighter to Light Wars. Each having their own strengths and weaknesses, none truly felt like a wholesome package. It outlooks, outsounds and outclasses its competition by a considerable margin. Indie developers playing ball in the App Store really need to step it up because right now – All Ur Bases R Belong To CS.One." - Jeff Effendi

Must Buy!
