In a world where sound shapes reality, players take on the role of Echo, a sound engineer who discovers a hidden dimension accessible only through specific frequencies. As Echo, you must journey through diverse environments—from eerie soundscapes to vibrant musical jungles—solving puzzles and interacting with characters made of sound while uncovering the conspiracy behind a missing melody that holds the key to harmony in both worlds. Along the way, players must carefully choose their sonic interactions, as each decision influences the soundscape, alters the plot, and affects their connection to the inhabitants of this auditory realm.
