is an abstract vertically-scrolling bullet-hell style shooter. There is no story, and most objects are made up of simple geometric shapes. The player has six different types of weapons which can be freely switched on the fly and do not upgrade. There are also three options which will follow the player's ship and change formation depending on the currently-selected weapon. These options will absorb and block incoming fire, and will grow as the player collects correspondingly-colored powerups. The player can also use a portion of an option's energy to execute a more powerful "sweep" attack. There are six stages, each with its own unique boss.
