Game Overview
A grim apartment block becomes a pressure cooker of suspicion in this 1955-set horror job simulator. Humanity lives under threat from doppelgangers: predatory impostors that copy people well enough to pass at a glance, but rarely perfectly. As the building’s new doorman, you spend each shift deciding who belongs behind the front door and who is wearing a neighbor’s face. That’s Not My Neighbor turns paperwork, portraits, and tiny visual inconsistencies into a surprisingly tense form of survival horror, balancing dark comedy with an unnerving, grotesque atmosphere.
Most of the action takes place at your security desk, where residents present identification, entry requests, and personal records that must match your files. You compare names, apartment numbers, appearance, dates, and other details, watching for mismatched documents or physical tells such as odd teeth, extra features, or subtly wrong faces. Genuine residents need to be admitted efficiently, while suspicious visitors can be refused or reported to the Doppelganger Detection Department for removal. Mistakes matter in both directions: letting a monster inside is disastrous, but wrongly rejecting an innocent person also damages your performance, creating a constant conflict between caution and speed.
Its strongest idea is how effectively it makes mundane clerical work feel dangerous. The hand-drawn 2D presentation recalls vintage cartoons and bureaucratic nightmare games such as Papers, Please, but its body-horror details and absurd personalities give it a very different flavor. Each run asks players to stay observant under pressure rather than rely on reflexes, while changing visitors, escalating oddities, and multiple possible outcomes encourage repeat play. Horror fans who enjoy deduction, unsettling humor, and spotting minute inconsistencies will get the most from it; players seeking action-heavy scares may find the desk-bound pace deliberate, but newcomers can still grasp its rules quickly.
