That's Not My Neighbor is a tense indie horror where deadly impostors lurk. Check IDs, scan faces, and decide who truly belongs inside or face the end.

Explore the terrifying world of That's Not My Neighbor

This is a psychological horror game combining simulation and deduction, set in a world where shapeshifting creatures (doppelgangers) infiltrate human society. You play as a doorman for the Doppelganger Detection Department (DDD), responsible for verifying residents' identities before allowing them into buildings. The task may seem administrative, but the consequences of one mistake can be...deadly.

The survival of the residents depends on you!

The gameplay mechanics are comparable to Papers, Please, but with a more pronounced psychological horror element.

You will have to:

Check identification
Compare portrait photos
Compare personal information (date of birth, apartment number, occupation...)
Observe unusual facial expressions
Listen to subtle details in speech

An extra tooth. A misplaced scar. An overly empty gaze. Just one small mistake, and you could:

Let the disguised creature into the building
Or inadvertently reject an innocent resident

Retro yet haunting art style

With a hand-drawn 2D graphic style reminiscent of 1950s cartoons, bright colors contrast with the eerie content, creating a characteristic sense of unease.

No monsters leap out of the screen. Only suspicion creeps into every frame. This suspiciously ordinary nature makes That's Not My Neighbor far more haunting than traditional horror games.
