Dodonpachi Resurrection, an iPhone port of DoDonPachi Dai-Fukkatsu, has two modes. Arcade mode looks like what you would expect from a Cave shooter. It’s the arcade game in your pocket. iPhone mode, literally, has a twist.
Players can spray bullets by touching their ship and spinning it with a finger. Cave developer “Masa KING” calls the attack “Spin-spin-pachi Resurrection!!”.
