That's Not My Neighbor: Trust no one at your door
What if the person knocking on your door isn't a person at all? Welcome to the ultimate security nightmare, where your job is to screen visitors and ensure no doppelganger slips through. That's Not My Neighbor turns mundane identity verification into a tense, paranoia-fueled horror game. As the doorman of an apartment building, every visitor must pass your inspection. Check their documents, verify their appearance, and cross-reference every detail. One mistake — letting a disguised monster inside — could have deadly consequences. The tension builds with each knock as you second-guess every face and every ID card.

How to Play That's Not My Neighbor
Welcome to That's Not My Neighbor! This is a unique horror and deduction game that is simple to learn but incredibly tense to master. As the building's security guard, your job is to check every visitor's credentials before letting them in. Examine each visitor's ID document carefully. Compare the photo to their actual face. Check for inconsistencies — wrong eye color, slightly different facial features, or documents that don't match building records. Use your Mouse to click through each inspection step, then choose to Approve or Deny entry. Let the wrong person in, and the consequences are immediate.
Disclaimer: These are the standard controls for this type of game on PC Browser with Keyboard/Mouse. The actual controls may be slightly different.

Tips & Tricks
Check the eyes first — doppelgangers often get pupil color or spacing slightly wrong
Keep a mental note of which apartment numbers are occupied vs vacant — visitors to empty units are immediate red flags
Don't rush. The timer is generous, and panic leads to missed details
If something feels 'off' but you can't pinpoint what, deny entry. False positives are better than letting a monster in

Frequently Asked Questions
Discuss: That's Not My Neighbor
I've never been so stressed checking IDs. The tension is unreal. Missed a doppelganger once and literally jumped.
Great concept and execution. Wish there were more doppelganger types though. By round 20 you've seen most patterns.
This game gave me trust issues with my actual neighbors. 10/10 would develop paranoia again.
