Evaluation

YAMIKKO TROUBLEMAKER is a free-to-play choice-driven psychological horror game that originally launched on February 12, 2025. The game is a self-contained narrative experience with a clearly defined set of endings (3 Normal Endings, 4 Game Overs, 13 Bad Endings, and 1 True Ending) and a stated playtime of 7–12 hours — all hallmarks of a complete, finished product. On December 3, 2025, the developer announced a full reset of the English translation, with a revised version due approximately one month later. That update shipped on January 16, 2026, as the English version release with new content — fulfilling the announcement. A bug fix for an achievement issue was also patched on December 20, 2025 during this period. Since the January 16, 2026 English release, there have been no developer announcements of additional content, roadmaps, or future updates. The game has no DLC listings and no unreleased content on the store. The developer has not indicated any plans for further development. The January 16, 2026 update represents the completion of the game's content as a finished package.
