About
Sent to investigate an abandoned apartment, you are tasked with documenting strange occurrences using the A.D.D. (Anomaly Detection Device)—a specialized tool capable of detecting and repairing irregularities.
At first, the apartment seems perfectly normal, but as you explore, reality starts to shift. Objects move on their own, shadows flicker unpredictably, and unnatural occurrences manifest around you.
You are trapped in a loop in which you must identify all anomalies in the apartment to progress to the next one. Missing even a single anomaly will send you back to the previous floor.
Your mission is to address every anomaly you encounter and find a way out of Flat 9.
This is a psychological horror game that may contain jump scares and intense moments. Player discretion is advised.

This is a nice experience that combines observation-based gameplay with occasional jump scares. The core mechanic of spotting differences between room iterations is engaging and keeps you on edge, making every playthrough tense and exciting. However, the limited number of differences can make the game feel a bit too easy after several runs, reducing its long-term replayability. I hope future updates will introduce more variations to keep the challenge fresh. Additionally, while the eerie atmosphere is well-crafted, the graphical effects can sometimes feel overwhelming. More customization options for visual settings would be a great improvement. Overall, Flat 9 is an entertaining horror game that, despite its simplicity, delivers a chilling experience. With a few tweaks and updates, it has the potential to become even better.
It may not revolutionize the genre, but it manages to elevate a simple concept with fun anomalies that don’t mess with your intelligence. These games don’t bother with deep storytelling. You start off emerging from an elevator, greeted only by a note instructing you to search for anomalies. The game’s setting is deceptively simple—a compact apartment with a living room, kitchen, and office. The layout is linear, ensuring you don’t waste time aimlessly wandering. But don’t let the straightforward design fool you. Every room is packed with detail, especially the office, which boasts a cluttered shelf and desk. Your task is to find and fix all the anomalies before progressing to the next floor. Unlike other games where you’re looking for a single, isolated difference, this game requires you to find multiple irregularities to proceed. That’s where the game’s signature scanner comes in. Point it at something unusual, hold down the button, and if the object truly is an anomaly, it will snap back to its original state. But it’s not always that easy. Make a mistake, and one of the three cross signs on your scanner will light up. Strike out three times, and you’re thrown back to stage one. And just when you think you’ve cleared a room and reached the exit door, the game throws a cruel twist your way. If you’ve found all the anomalies, you’re rewarded with stairs leading upward to the next apartment. Miss one, and the stairs lead back down to a previous level. Interestingly, falling back down the floors isn’t as punishing as it sounds. Thanks to the variety of fun and eerie anomalies scattered throughout, you’re never truly bored. From a table flipped upside down to a train outside the window rattling the entire apartment, most changes are apparent enough to spot. But others, like a circular clock swapping places with a square one, require a keen eye. The anomalies don’t just alter objects; they also deliver a good scare. A picture frame might leap off the wall when scanned, or your reflection could transform into a malicious doppelganger smashing through the mirror to chase you down. Once you finally reach apartment 9, the game switches things up with a survival challenge where anomalies occur at a relentless pace, daring you to outlast the chaos. Beat this nerve-wracking gauntlet, and you unlock Collector Mode, a handy mode that lets you see missed anomalies.
A short and sweet anomaly game with a twist at the end, enjoyable but minimal replayability.
A fun and atmospheric spot-the-difference game This game is a nice take on the Exit 8 style, offering a solid spot-the-difference experience with a slightly eerie atmosphere. Some anomalies are really tricky to catch, but that adds to the tension and immersion. What I appreciated the most is how the game respects the player’s time—it doesn’t punish you too harshly, allowing for a more relaxed yet engaging experience. Definitely worth a try if you enjoy this genre!
Flat 9 ist ein Anomaliensuchspiel, das eigentlich ziemlich cool ist. Man erwartet erst nicht viel, weil es schon viele Games dieser Art gibt, aber ich wurde positiv überrascht^^ Natürlich wurde das Genre hier nicht neu erfunden, aber es hat echt ein paar gute Scares und das Ende ist nicht einfach nur "toll, du hast alles richtig gemacht, da ist der Ausgang", sondern im letzten Raum erwartet einen ein kleiner Stresstest. Mir hat es echt Spaß gemacht und darum für mich ein Must-have, wenn man das Genre mag =)
이상현상이 좀 적네요 그것말고는 나쁘지 않아요 무섭거나 그렇진 않습니다. 공포게임인데 좀 아쉽네요 세일할때 사세요 [url=https://store.steampowered.com/curator/45555420-%25EB%258D%2594%25ED%258E%2598%25EC%259D%25B4%25ED%258D%25BC%25EC%2599%2580-%25EA%25B2%258C%25EC%259E%2584%25ED%2595%2598%25EA%25B8%25B0/]Steam Curator ThePaper <--큐레이터 주소[/url]
Flat 9 isn’t revolutionary, but it knows exactly what it is: a creepy, low-budget horror loop that’s perfect for one sitting. It excels at keeping you second-guessing yourself and punishing complacency. It won’t scratch every horror itch, but for fans of micro-horror games or those who enjoyed I'm on Observation Duty, this is a cheap and satisfying trip into madness.
Great Anomaly game. Well sorted anomalies, no unnecessary bugs.
La primera vez, tardé una hora o más. La segunda vez fue en 15/20 minutos. Lo jugué dos veces porque en la primera se me crasheó cuando iba a salir la cinemática de los créditos finales. Y la segunda vez también. Seguro que es problema de mi PC y no del juego. El juego está bueno porque no brinda mucho, pero es corto y no aburre por eso.
Definitely a thumbs up! This game is a great game to stream. It is challenging, but not overly difficult. Not too long but not too short. There is a great additional mode that allows you to find anomalies that you have missed during your first playthrough. And best of all, this game is CREEPY! I had goosebumps the whole time. If you can get it on sale, this game is a hidden gem. Rating: 8.5/10
