Note written 2026-08-23; the live figures above take precedence over any numbers in it.

Touhou Kaeizuka is a bullet-hell action game from ZUN's Shanghai Alice collective, the 17th mainline entry in the legendary Touhou Project franchise.

This 2022 title sits in a quiet zone: $668/mo residual revenue on a modest lifetime of $41k, near-perfect review sentiment (97.8%), and minimal promotional activity in 48 months suggest a self-sustaining niche product that has found its core audience and stopped chasing growth. The game is pure ZUN IP (not licensed), so acquisition of the executable and business would be clean. However, the studio shows 'fading' status and no developer posts in 53 months; this is a mature catalog entry for publishers seeking low-risk recurring revenue from a passionate but small fanbase, not a revival candidate. Most realistic play: publishing.

• Risk: Bullet-hell action is a saturated vertical; growth ceiling is structural, not promotional.
• Risk: No achievements, trading cards, or workshop support; limited feature set may limit discoverability and long-tail monetization.
• Risk: Developer studio status is 'fading' with 53 months since last public communication; IP stewardship risk if ZUN's activity continues to decline.
