Very scary - I liked how the paranormal entities moved across the screen. When you're focused intently on the details of the room, you don't expect any movement at all and it got me a few times. What I would say is that, on the second level, the object placed on the door handle in the room with the bin bags in it, was classed as 'monster/ghosts/alien' and it took a while to figure out because it looked like a brown object - I remember it being in another room as an anomaly and it was just classed as 'extra object'. The other thing was that, on the third level, the anomalies aren't consistent between camera shots (e.g., if a bottle has moved in one camera angle, it will have stayed in the same place in another angle of the same room). I'm not sure if this was intentional or not to make it easier but I know that it might be difficult to make it consistent given that it's based on real images that are tampered with. Maybe, if you were to update the game, you could make it so there could be multiple anomalies in one room - I know this will take longer to produce but I think it would throw the player off and definitely make it more difficult. The jumpscares were amazing though and the game is a really good recreation of Observation Duty. I really enjoyed - props to the creator(s).
P.S. - I didn't realise it was available on the app store - it would be really fun as a mobile app
