Picture yourself as a 1955 apartment doorman, clipboard in hand, facing what appears to be Mrs. Henderson from 3B. She has the right ID, knows her apartment number, and even mentions her cat Whiskers. But something feels… off. Her smile lingers too long, her eyes seem slightly wrong, and there’s an unsettling quality you can’t quite place. Yes, That’s Not My Neighbor is absolutely worth playing – this brilliant indie horror game transforms the mundane task of checking IDs into a heart-pounding psychological thriller.
Created by solo developer Nacho Sama, That’s Not My Neighbor has become an unexpected sensation on itch.io, blending bureaucratic tedium with genuine terror. The game’s premise is deceptively simple: prevent doppelgangers from infiltrating your apartment building by carefully screening each visitor. However, these shape-shifting creatures have perfected their human disguises, making your job far more challenging than it initially appears.
What sets That’s Not My Neighbor apart from typical horror games is its unique approach to fear. Rather than relying on jump scares or gore, it builds tension through paranoia and uncertainty. Every interaction becomes a high-stakes detective puzzle where missing a single detail could have dire consequences.
Key elements that make this game compelling:
- Psychological horror focus – Fear comes from doubt and suspicion rather than shock value
- Retro aesthetic – Pixelated 1950s setting creates nostalgic yet eerie atmosphere
- Detective gameplay – Players must analyze documents, behavior, and physical details
- Moral complexity – Wrong decisions have real consequences for innocent residents
- Replayability – Multiple scenarios and outcomes encourage repeated playthroughs
The genius of That’s Not My Neighbor lies in how it makes players question everything they see, transforming routine interactions into moments of genuine dread.
About That’s Not My Neighbor
Set in 1955, this unique title puts you in the shoes of a doorman who must identify dangerous imposters trying to infiltrate your apartment building.
The game’s creator, Nacho Sama, has crafted something truly special here. As a solo developer, they’ve managed to blend bureaucracy with horror in ways that feel both fresh and terrifying. When I first launched That’s Not My Neighbor, I expected a simple horror game. Instead, I found myself immersed in a world where every decision matters and trust becomes a luxury you can’t afford.
The pixelated art style might seem charming at first glance, but don’t let it fool you. This visual approach creates an unsettling contrast that enhances the game’s suspenseful atmosphere. Every character you encounter could be genuine or could be something far more sinister. The doppelgangers in this game aren’t just mindless monsters – they’re clever, calculating entities that study their targets with frightening precision.
What sets this game apart is how it transforms mundane tasks into heart-pounding experiences. Checking IDs becomes a life-or-death decision. Scrutinizing facial features turns into detective work that could save lives. The tension builds with each interaction, making you question everything you thought you knew about the people around you. This isn’t just horror for shock value – it’s psychological terror that stays with you long after you’ve stopped playing.

The core gameplay revolves around identity verification – a concept that sounds boring but becomes absolutely thrilling in practice. You’ll need to:
- Check identification documents for subtle inconsistencies
- Observe physical characteristics that might reveal imposters
- Listen carefully to responses that don’t quite match
- Make split-second decisions that affect everyone’s safety

The game’s pixelated art style creates a deceptively cozy environment that masks the underlying horror. This visual approach serves multiple purposes:
- Creates nostalgia for simpler times
- Hides disturbing details in plain sight
- Makes sudden revelations more shocking
- Enhances the 1950s setting authenticity
Character Interaction System
Every conversation matters in this game. The dialogue system forces you to pay attention to:
| Interaction Type | What to Watch For | Red Flags |
|---|---|---|
| Verbal responses | Hesitation patterns | Wrong personal details |
| Body language | Nervous behaviors | Unnatural movements |
| Documentation | ID inconsistencies | Forged papers |
| Personal knowledge | Tenant history | Missing memories |
Progressive Difficulty
As you advance, the doppelgangers become more sophisticated. Early imposters might have obvious flaws, but later ones require keen observation skills. This progression keeps the game challenging without becoming frustrating.
The detection mechanics evolve throughout your playthrough. What starts as simple ID checking becomes complex psychological profiling. You’ll develop instincts about who to trust and who to question further.
How to Play That’s Not My Neighbor
Basic Controls and Interface
The game uses simple mouse controls that anyone can learn quickly:
- Click to interact with characters and objects
- Drag documents to examine them closely
- Use the intercom system to communicate with tenants
- Access your reference materials for verification
Essential Gameplay Steps
Step 1: Greet Each Visitor
When someone approaches your desk, always start with a polite greeting. This sets the tone and gives you time to observe their initial behavior.
Step 2: Request Documentation
Ask for their ID and any relevant paperwork. Real tenants will have proper documentation, while imposters might hesitate or provide suspicious documents.
Step 3: Cross-Reference Information
Compare the visitor’s appearance with their ID photo. Look for:
- Facial structure differences
- Eye color mismatches
- Height inconsistencies
- Unusual scarring or marks
Step 4: Ask Verification Questions
Test their knowledge about:
- Their apartment number
- Other tenants in the building
- Recent building events
- Personal details from their file
Advanced Techniques
As you become more experienced, you’ll develop these crucial skills:
- Behavioral Analysis: Watch for nervous tics, unusual speech patterns, or responses that seem rehearsed rather than natural.
- Document Inspection: Learn to spot forged papers by checking watermarks, font consistency, and official stamps.
- Memory Techniques: Keep mental notes about each tenant’s characteristics, habits, and personal details.
Common Mistakes to Avoid
- Don’t rush through interactions
- Never ignore your gut feelings
- Avoid being too trusting or too suspicious
- Don’t forget to check all documentation thoroughly
The key to success lies in balancing efficiency with thoroughness. You need to process visitors quickly enough to avoid long lines, but carefully enough to catch dangerous imposters.
