The game uses a top-down vertical scrolling perspective. Players move the ship through each stage, shooting enemy craft and ground targets while avoiding dense projectile patterns. Power-ups expand the arsenal by upgrading weapons, changing shot behavior, or boosting support attacks. Some stages feature branching paths and hidden bonuses, and each area ends with a large boss encounter. Progress is based on stage completion, survival, and effective use of upgrades.

Keep your main weapon upgraded whenever possible, and be selective when swapping to a new weapon if your current setup suits the stage. During heavy fire, prioritize safe positioning over aggressive scoring. On a first playthrough, choose easier branching routes if available. Boss fights are usually best approached by learning firing cycles and staying close to safe lanes while maintaining pressure.
