The game follows Sumire Kirishima, a 19-year-old aspiring net artist who wants to perform on the same stage as her favorite idol. Players tap notes to music, and the type of notes hit causes the songs and story to branch, leading to multiple endings. A demo is available during Steam Next Fest, which runs until June 23. The full game is scheduled for release on PC via Steam in 2026. A second promotional video was also released, showing gameplay and some of the over 20 included songs. The game supports Japanese, English, and Simplified Chinese. Music production is handled by Yuta Ota, and the producer is Takafumi Suda.","whyItMatters":"G-Mode, known for its Data East archives and indie publishing on Switch and PC, backing a branching rhythm game with over 20 songs signals a bet on narrative-driven music games as a growing indie subgenre.","webCardHtml":"\u003cp\u003eThe game is a new project from LOVE ANNEX, a company that handles music production and creator management for anime and games.
