In a sprawling metropolis built over the ruins of a forgotten world, players take on the role of a sound archivist tasked with discovering and cataloging ancient, obsolete sounds that once defined human existence. As players navigate through different districts, they engage with quirky characters, uncover the city's history, and synthesize sounds into an audio library that can influence people's memories. Choices lead to different sound experiences, affecting the narrative and the environment. Can you restore lost memories or will you let the echoes fade into silence?
