Overview
Welcome to the Department of Doppelganger Detection (D.D.D.)! In That's Not My Neighbor, you step into the shoes of a doorman tasked with a critical mission: identifying and preventing doppelgangers from infiltrating an apartment complex. This unique job simulator blends science fiction elements with a subtly eerie atmosphere, challenging your observational skills and attention to detail.
Your primary responsibility is to scrutinize each applicant seeking entry. By carefully examining their documents and cross-referencing provided information, you must determine if they are truly human or a dangerous impostor.
The fate of the building, and potentially more, rests on your judgment. Will you grant access to a legitimate tenant, or will you deny entry to a doppelganger, perhaps leading to their capture by the D.D.D.?
The choices you make have real consequences.
