Liminal Observer: Spot Anomaly - Silence can be deceiving. Sharpen your senses and memorize every detail, because the liminal spaces, pools are changing. Inspired by the popular observation horror genre, this game challenges you to monitor high-definition surveillance feeds of eerie, abandoned locations. From the unsettling realistic liminal spaces, your job is to identify and report anything that shouldn't be there. Don't let the anomalies linger for too long, or your shift will end in a nightmare. OBSERVE AND REPORT Watch the CCTV cameras closely for any signs of change. Whether it's a misplaced object, a shifting shadow, or a flickering light—every detail matters. If you see something, report it immediately. Accuracy is the key to surviving the night. SINGLEPLAYER AND ONLINE CO-OP MODE (PLAY WITH ONE FRIEND) Don't face the silence alone. Join forces with friends in online Co-op mode. Scan the rooms together, share your findings, and cover more ground. Every extra pair of eyes increases your chances of spotting the most elusive anomalies. Think you have the sharpest eyes? Compete against your friends in extreme mode. Race to see who can report the most anomalies with the highest accuracy. Prove you are the ultimate Observer. KEY FEATURES: Immersive Liminal Atmosphere: Ultra-realistic visuals and sound design that capture the "poolcore" and liminal space aesthetic. Dynamic Anomaly System: Encounter various anomaly types including Extra Objects, Moving Objects, Faded Objects, and Intruders. High Replayability: Anomalies are randomized every session, ensuring no two playthroughs are the same. Fisheye Lens Perspective: Authentic surveillance camera feel for maximum immersion. The lights are flickering. The water is rippling. Something has changed. Do you have what it takes to report them all without running out stamina? icemoongames@gmail.com https://icemoongames.vercel.app
