11F

11F launched on April 19, 2024, developed by a solo developer (Sangwon Kim). In the days immediately following launch, the developer released several patches addressing bugs, added new languages, and made quality-of-life improvements. On April 22, 2024, the developer announced a planned "May Content Update" that would add a fourth floor area, and noted upcoming camera feature additions and localization work. However, that April 22, 2024 post is the last developer communication on record. There are no further news posts, patch notes, or announcements after that date. The promised May Content Update (4th Floor Update) and camera feature additions were never confirmed as shipped in any subsequent post. This means either those updates were released without announcement, or they were quietly dropped — but since there is no post-launch news beyond April 22, 2024, there is no evidence of any ongoing development activity. The developer had been posting frequently in the days right after launch (April 19–22), suggesting an active burst of post-launch support. The sudden and complete silence since April 22, 2024 — over two years ago — strongly indicates that active development has concluded. The game appears to have shipped as a largely self-contained horror adventure experience, and while some post-launch additions were planned, the development cadence never established a sustained pattern of major content releases. The game is best understood as a complete, shipped product.
