That's Not My Neighbor Entry

You take on the role of a doorman for a disturbingly creepy building. Each night, you must face a stream of visitors, subjecting each one to a meticulous entry exam. Your task is to determine whether they are ordinary neighbors or sinister doppelgangers attempting to infiltrate the building.

With only your wits and instincts to guide you, scrutinize each visitor's behavior, appearance, and responses. Make quick decisions to either grant them entry or capture them as doppelgangers and prevent them from entering. The tension rises as the night wears on, and the line between reality and horror blurs.
