The gameplay revolves around the concepts found in many SHMUP (shoot-em up) games. Each character has a standard attack known as a primary attack and a secondary attack known as a Shikigami. The Shikigami attack is more powerful but slows down or stops the player completely. There are 5 levels consisting of two parts. Each part has a boss at the end. An art gallery, music player, and replays of the dialogue cutscenes are unlocked throughout the game.
