You are not a simple gatekeeper; you are the final line of defense against an existential threat. The casual player sees two buttons: Green and Red. The elite analyst understands these as Accept and Reject—the fundamental levers of the scoring engine. This guide is for those who seek perfection, demanding a 100% success rate by exploiting the core loop of deduction and risk management. Forget simply "getting by"; we are here to optimize security clearance and maximize the perfect-identification streak.
The scoring engine in That's Not My Neighbor is built primarily on Risk Management (identifying impostors) and secondarily on Efficiency (speed of processing). A perfect clear rate is the multiplier; speed is the score generator. These three habits are non-negotiable for achieving S-Tier performance.
Golden Habit 1: The Triple-Check Protocol - In a high-stakes deduction game, the most common failure state is the single-point-of-failure check. The doppelgangers are designed to fail in subtle ways. This habit mandates that you never rely on a single discrepancy. Always confirm the ID photo (must match 100%), the physical description (clothing, height, obvious features), and the required documentation. This is slow initially, but it ensures a flawless run, which is the ultimate score multiplier. WHY IT IS CRITICAL: A single mistake ends the perfect streak. A perfect streak grants exponentially higher scores than raw speed.
Golden Habit 2: The Documentation-First Scan - Most players begin by looking at the face. Elite players immediately scan the provided documents. The ID card, permits, and any special forms are the hard data the game provides. The doppelgangers’ mimicry is strongest in their physical form but weakest in their paperwork. The fastest way to confirm a genuine resident is a perfect paperwork match; the fastest way to confirm an impostor is a paperwork mismatch. WHY IT IS CRITICAL: Paperwork defects often require the least time to verify, allowing you to quickly hit Red and move to the next applicant, boosting your efficiency score.
Golden Habit 3: Anomaly Categorization - Do not view discrepancies as just "errors." Categorize them instantly into Soft Anomalies (e.g., slightly different shirt color, minor behavioral quirks) and Hard Anomalies (e.g., incorrect D.D.D. stamp, mismatched ID photo, extra/missing limbs). If the applicant presents a Hard Anomaly, the decision is instant Red. If only Soft Anomalies exist, you proceed to the final, high-risk check (verbal/behavioral). WHY IT IS CRITICAL: This habit standardizes your decision-making process, eliminating hesitation, which is the primary enemy of the speed bonus.
The key to high-score runs is not avoiding errors, but optimizing the rejection process. The highest-scoring actions are correct rejections, as they confirm security integrity and prevent a game-ending mistake.
Advanced Tactic: The "Micro-Diff" Interrogation
Advanced Tactic: The "Behavioral Trap" Trigger
Most players think that the goal is to process everyone as fast as possible to maximize the speed bonus. They are wrong. The true secret to breaking the 500k score barrier is to do the opposite: prioritize processing the most suspicious applicants first, even if it interrupts a fast flow.
Here's why this works: The game's difficulty and scoring curve are heavily weighted toward identification reliability. Mistakes are heavily penalized, and they often occur when the player is rushing a highly complex case. By identifying the most complex, multi-layered cases (those with numerous Soft Anomalies) and assigning them maximum cognitive effort at the expense of the speed bonus, you guarantee the perfect streak. A perfect run earns a massive end-game multiplier that far outweighs any lost time bonus from five or six quick, simple rejects. Maximize the streak; the score will follow.
The system rewards surgical precision, not frantic speed. Adapt, analyze, and achieve perfection. Your watch begins now.

You must pay close attention to the details provided on their identification documents compared to their actual appearance, behavior, and speech. Look for inconsistencies, discrepancies in their ID photo, or unusual physical traits. Any mismatch between the official ID and the guest is a red flag indicating a potential doppelganger.

This game is surprisingly deep for an iframe title. The deduction element is genuinely engaging, forcing you to pay close attention to the ID details and subtle changes in the 'neighbors.' The balance is excellent—it starts easy but ramps up the difficulty quickly. My only wish is for a detailed score breakdown at the end of each shift. Great work, devs!
Addictive score-chasing loop. The thrill of getting a perfect day (no false positives or negatives) is immense. I've reset so many times just to beat my best score of 15 successful shifts. The RNG on the doppelgangers' subtle flaws is the real challenge. Need a global leaderboard, though. I want to see how I stack up globally!
Solid time-killer for my commute. Rounds are short enough that I can finish one before the next tube stop. It’s fun to try and spot the difference quickly. My only minor gripe is the sometimes confusing ID font, makes me miss a detail and get fired lol. Still, highly recommended for a quick fix.
As a fan of the 'Papers, Please' aesthetic blended with light horror, this hits a sweet spot. It doesn't have the deep narrative complexity of other deduction sims, but the tension is palpable when you have five people lined up and only seconds to check their documents. It needs more variety in the doppelgangers' tells, though—it gets a bit predictable after a few hours. Still a strong entry in the genre.
OMG I was so scared the first time I pressed the wrong button! I'm usually bad at horror games but this one is so fun because it's more about being smart than jump scares. I'm completely hooked and can't wait to play it again tonight! Five stars, the music is so creepy!
The core loop of observation, comparison, and rapid decision-making is excellent. It’s a perfect example of 'easy to learn, hard to master.' The psychological pressure of making a mistake that lets a monster through is a fantastic design choice. I would love to see an 'Insanity Mode' where the documentation details occasionally shift or are smudged to increase the difficulty. A fantastic strategy game disguised as horror.
