Doorman horror game: spot the impostor before you open the door

The problem

Games like Papers, Please and That's Not My Neighbor show that players enjoy careful checking under pressure. Many followers copy the same apartment-intercom setup. There is room for short, replayable takes with new settings and rules that change each night.

For: Horror-lite fans · Streamers and their viewers · Fans of document-checking games

Why now

No, I'm not a Human sold 1 million copies within about six months of its September 2025 release, and the anomaly-spotting game The Exit 8 passed 3 million copies in September 2026.
