In a fragmented world where echoes of past identities linger, players assume the role of Echo, a sentient mirror that can absorb and project the memories of those it reflects. Set in a surreal city affected by a mysterious phenomenon, the inhabitants have collectively lost their sense of self. Players must interact with different characters, each representing a different identity, and piece together their own backstory by choosing who to echo. Choices will lead to dramatic consequences, affecting not only the characters' lives but the very fabric of the city's reality. The ultimate goal is to uncover the truth behind the identity crisis and restore everyone's fragmented personas, including Echo's own unexplored essence.
