Ninja vs Samurai has been ported to iOS, using cocos2d. It is available for iPhone and iPad and features retina graphics (where available) in a universal app which works for all iOS 5 devices.
Due to the limitations of the screen size not all of the levels from the desktop version has been ported over, but the game features a whole bunch of new levels (totaling 120) and there is always room to add more.
great work :)
