Disoriented

Disoriented launched on November 21, 2016 as a compact first-person puzzle game with 30 levels. In the months following launch, the developer shipped several patches adding features such as keyboard remapping, controller support, checkpoint improvements, and a leaderboard. The most substantive post-launch addition was Update 1.1 on May 13, 2017, which added 6 new levels and a camera-switching feature. After that update, the final developer communication was a bug fix on December 2, 2017 addressing a character falling-through-floor issue. There have been no developer posts of any kind since December 2, 2017. The store description describes a fixed 30-level puzzle game with no mention of ongoing content, seasons, or planned additions. No DLC has ever been listed. The game appears to have shipped as a self-contained product and reached its final state with the December 2017 patch.
