Set in a quirky, steampunk city called Harmonia, players assume the role of a disgraced former composer who unwittingly created an army of sentient musical instruments. After their popularity surges, the instruments gain sentience, and chaos ensues as they begin a revolt against their creator. Players must navigate the city, interact with zany characters—both human and instrument—and make choices that influence the narrative, solve riddles based on music theory, and restore harmony before the city is overtaken by this instrumental uprising. The game cleverly combines elements of humor and drama while addressing themes of creativity, purpose, and the relationship between creators and their creations.
