The game uses a top-down or near all-direction combat layout where the player moves a ship freely while firing independently in another direction. Stages are built around successive enemy waves, often spawning from multiple sides to pressure the player. The core skill lies in separating movement from aiming, dodging threats while maintaining fire on priority targets. As the game progresses, enemy speed, density, and attack pressure increase, making route awareness and safe spacing more important.

Learn the dual-stick rhythm early so movement and aiming become instinctive. Stay around the lower-middle area of the screen whenever possible to keep escape routes open to both sides. When fast enemies appear, remove the closest threats first instead of chasing distant targets. If waves spawn from fixed points, pre-aim at entry paths to thin them out before they surround you.
