That's Not My Neighbor is a horror game, you play as a doorman at an apartment building. Your mission is to prevent doppelgangers from entering the building.
In a world where doppelgangers are becoming more and more common, the Doppelganger Detection Department (DDD) has assigned you an important task: protect the building from the intrusion of impostors. With your keen eyes and meticulous observation skills, you must distinguish between real residents and doppelgangers trying to blend in. Every time someone comes to request to enter the building, you will have to carefully check their features such as face, clothes, and posture... to make the final decision.
Look closely at every detail of the person's face, clothing, and posture. Compare them to the information on the resident list. Don't forget to check identification. There may be small details like a signature, photo, or stamp that don't match. The way the person moves, talks, or responds to your questions can also be important clues. Use tools like a magnifying glass to zoom in on small details on the face or clothing. You can use the phone to call the resident's apartment. If no one answers, it may be a suspicious sign.
