Horizontal shooter. SNES version removes some opening scenes from the original X68000 version but offers a more enjoyable game by allowing you to cycle between weapons and movement speed, also has a different soundtrack which is just ok. Gives you a health bar and weapon powerups will also add to your health. Some backgrounds and good mechanics that allow different weapon types, missiles, and sacrificing weapons as different types of bombs can be strong options at different times but it can take a long time to see a particular kind of weapon drop again and some of their bomb features are very lacking compared to others. Dull enemy and boss design with little animation to them, overly long, and full of fairly repetitive sections where the same patterns of enemies can keep coming at you two or three times more than is normal for the genre. Apart from stage five which has you destroying a ship where the screen only scrolls based on your movement and you can blow up parts of it and its guns to enter little passages to get to three openings that lead you to mini boss fights, it's a fairly generic shooter (and apart from the US box art that they chose just to confuse people into having to look at a generic shooter).
