Neighbor's Doppelganger challenges players to sharpen their detective skills in an intense setting where observation, memory, and quick decision-making are essential. This casual game with a mild horror theme casts you as the building protector, tasked with safeguarding the residents from dangerous intruders disguised as ordinary people. Your mission? To identify and eliminate the impostors before they infect the entire building.
As the building controller, you are responsible for reviewing the residents' list and apartment data. Each day, new characters apply to enter the building, and your job is to verify their identity. Keep an eye out for any discrepancies in their personal information or behavior. The key challenge lies in spotting the impersonators, who are incredibly skilled at mimicking real residents.
