弹幕音乐绘 ～风雷幻奏曲～ / Barrage Musical ~A Fantasy of Tempest~

Barrage Musical ~A Fantasy of Tempest~ launched on October 7, 2017. In the months following release, the developer issued several patches adding localization support (English and Japanese) and new features. The most substantial post-launch update was version 1.10, released on January 14, 2018, which added Ultra Mode (a high-difficulty tier), a gallery system with unlockable art, and additional achievements. That update represents the peak of post-launch content development. After January 2018, the only developer communication was a July 2019 post, which was an announcement for a separate, unrelated free game called "Touhou Fantasia" — not a content update or roadmap for this game. There have been no news posts, patches, or developer communications for this game since January 14, 2018 (nearly 8.5 years ago as of today). The game has no unreleased DLC listed, no season pass, and no roadmap or outstanding commitments. The developer has never announced additional content beyond what has already shipped. The game launched as a self-contained rhythm shoot 'em up and received a modest round of post-launch polish and feature additions within its first few months. All signs point to the game having reached its final state with the 1.10 update in January 2018.
