This is a technical marvel that proves that high-intensity danmaku can thrive within a browser. While it lacks modern amenities like controller support and utilizes a bare-bones arrow-key control scheme, it captures the raw, unfiltered spirit of the Touhou Project doujin scene.

The gameplay is a punishing yet rewarding experience that stays true to the wall of death philosophy. You'll find all the standard mechanics here, including focused movement for precise hitbox control and screen-clearing bombs for when the patterns become a spirograph going horribly wrong. It introduces some unique quirks, such as the push of the "P" key that fully restores lives but instantly invalidates a one-credit clear, ending your run at the conclusion of a stage. Despite the impressive engine, the game can be a sensory assault with foggy backgrounds making the danmaku difficult to see.

You'll be in for a treat with a soundtrack composed and arranged by Selene. It blends original themes and tracks inspired by official tunes and those out of Len'en. While some tracks are punchy and iconic, others such as the notably short repetitive loop for Yua Kurosawa can be a test of patience during the character's boss fight. Overall, if you can forgive the lack of score and grazing, this game is a hidden gem and a labor of love that stands as a beautiful, chaotic alternative to the monetization-heavy landscape of modern gaming.
