About this game
In a decaying psychiatric hospital run by a manipulative psychiatrist, patients wander the halls with no memory of who they are or what was done to them. But you remember. You're not a patient. You're here to find your sister.
Disguised as one of them, you must navigate a collapsing system of secrets, paranoia, and experimental treatments. Blend in. Stay undetected and uncover the truth.
The deeper you go, the more your mind and your body begin to betray you.
