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.
30-60 minutes
The ability to spot differences is key to overcoming the challenge.
Some anomalies are easy to detect, while others are more subtle and require closer observation.
If you encounter frame lag or stuttering during gameplay, you can adjust your graphic settings to improve performance. Reducing these settings can lead to a smoother experience, allowing you to fully enjoy the game without interruptions.

Под пивко пойдет. Так чисто поискать аномальки немного, номана. Но если долго играть, то начинаются пенистые выделения из киски
Rendben van.
Short and sweet, 100% the game in an hour
Gioco sulle anomalie unico nel suo genere con tante chicche particolari che sorprendono! Consigliatissimo per gli manati del genere!
Solid little anomaly hunting horror game! Good jumpscares. Sound design was 👌🏻 My playthrough: My apartment is HAUNTED | Flat 9 https://youtu.be/K4jVvI0I95U
Un concept très sympa où l'on est en quête d'anomalie. La progression est plutôt simple et dès que l'on a compris le mécanisme cela va vite. L'appartement 9 accélère le rythme et nous fait stresser. Comptez 40 minutes environ, pour le prix c'est un bon jeu pour se détendre en quelques minutes. Découvrez mon let's play : https://www.youtube.com/watch?v=tsuBB-8aOfk
This was so good, definitely worth a play through if you like exit 8 like games!
I absolutely love anomaly games and I really enjoyed the concept of this one. I did get a good scare from one of them as I was screensharing for my friend and they burst out laughing because I had never screamed that loud before out of fear and shock.
8/10 I am pleasantly surprised how much I enjoyed this anomaly game. A few jump scares got me. The anomalies are unique and interesting. You walk through a flat and scan an anomaly with the scanner to fix it. There can be multiple on each level. If you get it wrong you go back one flat instead of starting back at the beginning. You can die which will start you at flat one, but for the most part the game is very forgiving, which I appreciate. It makes it more fun with less frustration. When you reach flat 9 you get a cool mini survival game. There is also a collectors mode where you can play once you've beaten the game to 'collect' all anomalies that you haven't seen yet. Easy to get all achievements. You can change sensitivity, gamma, and remove motion blur. There are other options as well to help with your experience playing. It would also be nice to have a zoom feature, right mouse button, to see details better. The graphics look good, including your character, I can tell the dev put a lot of work into this game. Pretty cool game overall and I think it's worth the price.
Great game! Short, sweet, and has effective scares that keep you guessing! I have played countless horror games, and anomaly-hunting games. I can say that Flat 9 is up there as one of the best of the genre. Of course, I would have loved it to be longer. But for what it is - Flat 9 is very well made and doesn't overstay its welcome. Can't wait to see more from this dev!
