頭痛

頭痛【資料館編】 is a free-to-play, first-person horror exploration game released on November 20, 2021 by solo developer MONZEN. The game launched as a self-contained experience with 5 endings and an estimated playtime of 20–60 minutes — a compact, finished product by design. Post-launch activity consisted of a single bug fix in November 2021 (addressing a VR startup issue and a volume bug). The developer's most recent news post, from August 1, 2022, announced a separate paid game ("Illusion 幻覚") rather than any new content for this title. There is no DLC, no announced future content, no roadmap, and no developer statements suggesting further updates to this game are planned. The game shipped as a complete package and has received no content additions since launch.
