This game is an anomaly finding (difference finding) walking simulator. Game description: Get out of the building via the stairway. Observe the levels carefully for a successful exit. If everything is consistent in the level with the baseline state, proceed. If you observe any anomalies, turn back! Once you're out of the building, you can start the game all over again to experience all the anomalies! --- Attention! This game is a result of learning Unreal Engine. All sound files, 3D models, and textures are sets of free resources downloaded with some modifications. Have fun!
