A psychological horror set in a deserted apartment, where you're trapped in a relentless cycle. Armed with a strange device, you must find and report every anomaly to escape. Can you make it past 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. GameplayYou 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 WarningThis is a psychological horror game that may contain jump scares and intense moments. Player discretion is advised. Play Time30-60 minutes DifficultyThe 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 TipsIf 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.
