You control a female spaceship pilot who is sent on a mission into deep space.

This is a side-scrolling space shooter. You control a female spaceship pilot who is sent on a mission into deep space to save the Earth from an assault by an evil dragon from another galaxy. Moving vertically or horizontally, you must avoid or kill the enemies and make it to the end of the level alive, where a boss battle awaits you. You can switch at any time between two modes: normal spaceship and flying robot. The two forms use different weapons and also have different special abilities. While the spaceship can fire destructive lasers for major damage, the robot can raise a shield that will protect you from enemy attacks for some time and instantly kill anything that touches it. You can either charge attacks by holding a button for several seconds, or collect icons during your flight to release it quickly afterwards.
