That's Not My Neighbor is a unique 2D horror game in the "job simulation" genre. The game puts you in the role of a doorman in an apartment building in 1955, where you face bizarre situations: the discrepancy between real neighbors and doppelganger creatures capable of shaping human identities.
Your mission is to check each passenger's identification to determine if they are a doppelganger. Accidentally dropping a doppelganger will cost you points and risk death at the end of the game. Conversely, calling the wrong person (DDD) will leave you wondering who died afterward. Not My Neighbor requires attention to detail and quick, sound judgment. Every decision has consequences, and you must think carefully before acting. Prepare to be the best gatekeeper or the last survivor in this mysterious building.
