Maru Works — 『椿家の初七日』

Field notes

The project has already established a small public infrastructure around the game: a Steam store page, screenshots, two trailer stages, dated announcements, and separate streaming guidance. The homepage identifies it as Maru Works' first work and gives a planned Steam date of November 13, 2026. Its core setup is unusually concise: a Japanese-style mystery adventure in which each of four characters may be the culprit.
