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.

The game includes a variety of modes: achieve different endings based on your performance in campaign mode, beat your high score in arcade mode, solve various puzzles in nightmare mode, and design your own tenants in custom mode.
