That's Not My Neighbor

• My Website

Amid the indie boom, That’s Not My Neighbor emerged as a different phenomenon: a minimalist but sharp horror game where players don’t fight, don’t run away, but confront the horror through… bureaucratic procedures. Set in 1955, you play as a doorman of an apartment building, with a single but stressful responsibility: preventing imposters – doppelgangers who can subtly mimic humans – from entering the building.

The work was developed by Nacho Sama, an indie game maker who turned rough pixels into a world that is both familiar and unsettling. The seemingly slow pace of gameplay draws players into a series of tense confrontations: checking papers, observing small details, waiting for even a single breath to go awry. Every door opening is a gamble, and every decision can cost someone’s life.

It’s this combination of psychological horror, deductive reasoning, and quirky “office” vibe that makes That’s Not My Neighbor one of the most talked-about indie games of recent times. In the online version of thatsnot-mneighbor.io, the community constantly shares startling moments, life-saving judgments, and the suspense of realizing that the person at the door… is not right.
