As the monsters harmonize to unlock different areas of their vibrant yet chaotic world, you must solve musical puzzles, unravel their backstories, and help them find their unique voices. Each monster has its own distinct rhythm and style; by piecing together their melodies, you restore balance to their realm and unveil the mystery of why music is fading.
