Sophia Rhythm Adventure Demo Shown At SAGA Barcelona Game Fest 2026
A rhythm game built on classical music without a strong beat is a harder design problem than the genre's drum-and-electronic standard, and the demo answers it by mapping notes to the cello's bowing and rubato rather than to a backbeat.

Claysoft, an emerging local developer, brought a playable demo of the rhythm adventure "Sophia" to SAGA Barcelona Game Fest 2026, held in Barcelona from October 9 to 11. The game pairs picture-book 2D art with classical music, following a young cellist named Sophia who uses her cello against enemies embodying the heart. The demo covered the first of 12 planned boss battles. No release date is announced, and the demo is not yet public on Steam.
The demo on the show floor was a fight against the first boss, one of 12 the developer plans to include. Notes on screen track the cello's bowing, note sustain, and the performer's tempo fluctuations rather than a steady drum count.
That choice changes how the game is played. Instead of bouncing to a heavy beat, the player sways slowly left and right with the melody, treating the cello line itself as the rhythm. The setting is a quiet world where music and color are draining out of people's hearts, and Sophia retraces memories sunk into oblivion while talking with people she meets in crumbling cities.
