About Flat 9

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.

Gameplay

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.

Content Warning

This is a psychological horror game that may contain jump scares and intense moments. Player discretion is advised.

Play Time

30-60 minutes

Difficulty

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.

Performance Tips

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.

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

Flat 9 is a fun little anomaly hunt game. A more juvenile take on the genre that doesn't have any bloodshed or gore and only one "dangerous" anomaly and the jumpscares are a bit silly and childish. Some of the anomalies are extremely subtle and very clever. If you have younger family members interested in horror or anomaly hunt horror, I would recommend this one. It's also far more forgiving than other anomaly hunts. Instead of being booted all the way to start, you just start from the last level. You also get 3 chances per level to mess up. Overall, a tidy and neat little game if you like this specific genre.

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.

I like this one. There are some anomalies that kill you, which is always lame. It's mostly horror themed. You have to point out the anomalies, so there's no luck involved. Game takes about 40 minutes to fully complete.
