That's Not My Neighbor
That's Not My Neighbor is a doppelganger detection game set in an apartment building in 1955, where you work as the doorman for a special government department. Your job is to check every resident who wants to come in and stop the copies trying to sneak inside.
Working the Door in That's Not My Neighbor
Each day, a line of visitors arrives at the door. Some are real residents, while others are doppelgangers who look almost identical. You must compare them with your records before letting anyone in.
Your desk holds the tools of the trade. ID cards, entry requests and a list of residents help you check names, photos and apartment numbers.
Mistakes have consequences. Letting in a copy can lead to disaster, and turning away a real neighbor has its own problems.
Spotting Doppelgangers in That's Not My Neighbor
The copies are clever. They might have a wrong detail on their ID, an odd feature on their face or an entry request that does not match. Some differences are obvious, but many are subtle.
The rules change as days go by. New documents and procedures are added, and you must keep up with them while the line grows.
The department provides some help. You can call apartments to confirm residents are at home, which can reveal an impostor.
Style and Humor
The game mixes creepy and comic in its art. Characters are drawn in a distinctive cartoon style, and the doppelgangers often look hilariously wrong once you notice the flaw.
That mix of humor and horror has made it a favorite for streamers. Viewers love spotting the strange details and reacting to the player's decisions.
The setting adds charm. The 1950s aesthetic gives the building a retro feel that contrasts nicely with the bizarre visitors.
Why It Fits Suzy Says! Fans
Suzy Says! asks you to notice whether a command has the right prefix. This game asks you to notice whether a face has the right features. Both reward attention and punish lazy assumptions.
Both also feature a dangerous visitor at the door. Suzy's special friend and the doppelgangers share the same goal: getting inside.

Modes and Endings
The main mode tells a story across several days, with events that change the building and its residents. Different choices lead to different endings.
A harder nightmare mode challenges experienced doormen with more visitors and trickier copies.
Extra options let players test their skills for as long as they can keep the building safe. Many fans return to beat their best record.
Tips for Doormen
Check everything, every time. Even familiar residents can be copied, and skipping a step is the easiest way to make a mistake.
Use the phone. Calling an apartment is one of the most reliable ways to confirm a resident.
Stay calm when the line grows. Rushing leads to mistakes, so focus on one visitor at a time.
That's Not My Neighbor is a funny, creepy and addictive test of attention. Take your post at the door and keep the building safe from the copies.
