Vertical scrolling bullet hell shooter where you dodge intricate patterns of projectiles across six stages. You pick one of four playable characters—each with distinct shot types and movement speeds—to fend off a Lunarian invasion of Gensokyo. The hook: two difficulty modes fundamentally change how you approach survival. Legacy Mode gives you lives and bombs like traditional shooters. Pointdevice Mode checkpoints each segment, letting you retry sections without restarting the stage, but removes extra lives entirely. Boss fights layer overlapping bullet waves that demand tight movement and pattern recognition. The story involves Lunarians purifying Gensokyo to make it habitable after trouble in the Lunar Capital, but the real draw is mastering increasingly dense projectile choreography. Suits players who want unforgiving precision or those who prefer practicing tough sections in isolation.
