That's Not My Neighbor is a detective puzzle game. You are going to be the new janitor in this building when you are watching the tutorial video. Your job is to determine if the person who wants to enter the building is a monster. The monsters can transform into anyone and imitate them. Some monsters are not good at imitation and may develop flaws. You have no choice but to pay attention to the image of your neighbors. At the same time, remember to fill out checklists for each neighbor.
