Evaluation
AREA 4643 launched on December 21, 2018, and received one notable post-launch update on May 24, 2019 (v1.1), which added a new playable character (Ninja Slayer-san) and expanded Stage 3. The game's store description still advertises a fourth playable character slot listed as "???" with the text "more characters will be released in next version!" — indicating the developer had publicly committed to additional content at the time of that last update.
However, the last official communication from the developer was that May 24, 2019 post. As of June 26, 2026, over seven years have passed with no further updates, announcements, or patches of any kind. The promised character and any other planned content have never shipped, and the developer has not addressed the outstanding commitment. This extended silence makes it impossible to confirm whether development is continuing or has quietly ended.
