The game features three difficulty modes, Trial, Normal and Marathon. The ship has two weapon shot types. A standard forward shot, which I believe seems to be more powerful in a head on situation, and a spread shot that creates a cone-shaped pattern. This comes in useful when you have a barrage of enemies on both sides of the screen. There is also a shield which becomes vital (if you remember you have it) in tight situations. This replaces the more traditional 'bomb' usually found in the genre. You pass from stage to stage with increased waves of enemies and harder bullet patterns, and given an overall hit percentage at the end of each stage, amounting to higher scores.

In this vertical scrolling spaceship shooter, you control a ship that can change its polarity at will. As blue/white, the ship can easily destroy red/black enemies, and vice versa. Bullets of your polarity can be collected to fuel your energy gauge, but those opposite will kill you. Destroying an enemy ship causes them to fire revenge bullets which can be absorbed and fired back by the player. Different difficulties exist to change exactly how you interact with polarized points, or how they appear. It is the spiritual successor to Radiant Silvergun, featuring similar level and boss design, as well as it's buddhism inspired themes and aesthetics. Both are directed by Hiroshi Iuchi, who also composed Ikaruga's soundtrack.
