六阶谜题 six-step mystery

六阶谜题 launched on April 23, 2020. In the weeks following launch, the developer shipped several updates adding features and fixing bugs, followed by one notable content addition on August 10, 2020 — a short chapter appended to one of the game's endings (v1.40). That appears to be the last meaningful content added to the game. After August 2020, the developer went quiet for over four years. The next recorded communications, in September 2024, were purely technical: an engine update (v1.42, September 18, 2024) to improve GPU compatibility, followed immediately by a hotfix (v1.43, September 19, 2024) to address a regression introduced by that engine update. Neither of these constitutes new story or gameplay content — they are maintenance patches to keep the game running on modern systems. There are no unreleased DLC listings, no announced roadmap, no developer statements promising future content, and no sustained pattern of major content releases that would suggest more is on the way. The game appears to have shipped as a self-contained visual novel/mystery adventure and received one content addition in its first few months of life. The developer's activity since then has been limited to keeping the game functional. The game's content was effectively complete as of August 10, 2020.
