In a post-apocalyptic world where echoes of the past linger in the air, you play as Echo, a charismatic and snarky audio engineer tasked with uncovering the truth behind a series of mysterious echoes that haunt the remnants of civilization. Each echo represents a memory from different characters' lives, and it's your job to interact with these echoes to piece together their stories while navigating relationships, moral dilemmas, and environmental challenges. Choose dialogue and actions wisely as each decision shapes not only the echoes you unlock but also your character's fate and the world around you. Will you solve the mystery of the echoes or become lost in their haunting melodies?
