Collect items to upgrade Koishi's survival capabilities, allowing her to venture deeper into the caves. Why Koishi Komeiji?

The choice of Koishi as the protagonist stems from her immense popularity in the Touhou fandom. Originally appearing as an Extra Stage boss in Subterranean Animism , her ability to manipulate the subconscious and her "unconscious" lifestyle make her a perfect fit for an aimless wanderer in a dark cave setting.

Navigate dark, interconnected cave systems filled with hazards.

Developed by and available on platforms like Booth, the game is a 2D side-scrolling adventure. The latest V1.04 update focuses on refining the player experience and expanding the "defeat" mechanics that give the game its title.

Battle specialized enemies. Survival is the goal, as losing leads to specific defeat animations and events.
