Welcome to That's Not My Neighbor

Step into the eerie world of That's Not My Neighbor, a horror simulation game that combines bureaucratic precision with psychological tension. Created by Nacho Sama, this fan-made indie hit on Itch.io draws players into a 1950s apartment complex plagued by mysterious impostors known as doppelgangers. You play as a doorman for the Department of Doppelganger Detection (D.D.D.), tasked with a deceptively simple mission — decide who’s human and who’s not. But as the nights drag on, paranoia grows, and the line between truth and imitation starts to blur.
