That’s Not My Neighbor is a chilling indie horror game that blends psychological tension with detective-style gameplay. Set in a 1955 apartment building, you step into the shoes of a doorman whose job is far from ordinary. On the surface, it seems simple—check IDs, open doors, and keep the residents safe. But there’s a sinister twist: doppelgangers—perfect human imposters—are infiltrating the building, and it’s up to you to stop them before it’s too late.
