Players find themselves in a transdimensional space known as the Corridor, a place where echoes of past choices manifest as adversaries. As they navigate the disorienting twists and turns of their personal memories and fears, players must interact with their past selves and choose which echoes to confront or embrace. Every decision alters their path, leading to multiple possible endings that reflect the consequences of their actions and the burden of their regrets. Can they find redemption, or will they be consumed by the darkness of their own making?
