About the Game
The Department of Doppelganger Detection (D.D.D.) needs you!
Immerse yourself in the experience of working as a doorman in an apartment complex infested by beings that take on the appearance of your building's neighbors.
That's Not My Neighbor is a job simulator with science fiction elements and a slightly eerie aesthetic that will test your sense of observation and attention to detail.
Your job as a doorman is to allow or deny access to applicants seeking entry to your building. You will use tenants' documents and information to determine whether the applicant is truly human or not.
You will have the power to decide who enters the building and who is rejected or captured by the D.D.D. for extraction.
Include a variety of game modes: achieve different endings based on your performance in Campaign Mode, beat your score in Arcade Mode, test your skill in Nightmare Mode, and design your own tenants in Custom Mode.

Official update history
* Also I fixed the bug when the photo of Alf was showing instead of the Afton when he is missing.
* Another minor bugs that I found were fixed.
Thank you for your patience and if you ever ecounter another bug please let me know here I will check it out! I know that there is one that shows this text when ask to doppelgangers with small faces "APPEARACNE_SMALL_FACE", I still don't know why is this happening, I even test it and works fine for me but it seems that it is still there but somehow I can not see why, but until I figure it out that bug will be there for a while.
Also just to help you with something, If a neighbor left their documents at home and there is nobody on the apartment you can just deny the entry or let them in, when it is something wrong with the id or entry request like the id number for example, the document always show up if you ask them about it, so if they left the document at home then that document is fine, but they can still be doppelgangers, maybe something wrong with their appearance.
* The emergency button is now available after archiving the list, so you can use the button even after archiving it.
* A button has been added to skip the clown in the campaign mode for those who don't want to play with it.
* The bug that caused all neighbors in custom mode to have the same job has been fixed.
Message for veteran players:
I’ve noticed some confusion regarding the hats and the information that was removed from the folder.
In this new version, whether or not you wear a hat doesn't affect whether a person is a doppelganger. The answer to questioning their appearance was a mocking reference to myself for adding that mechanic in the old version.
In summary, not wearing a hat is not an issue and doesn’t need to be verified by call, which is why that option doesn’t exist in this version.
As for the removed information, only what is relevant has been kept, such as Nacha's eye color for example. Everything else can be verified with photographs, so it no longer serves any purpose and was removed to make the photos larger.
The important text box for colors when Nacha's doppelganger appeared displayed more text than intended.
Margarette's apartment number in today list.
An error occurred with the questioning interface after pressing the emergency button.
Other minor bugs.
