Visually and in terms of jump scares, it’s great for an anomaly game—no question about it. But for me personally, it’s just too hard. Even when the missed anomalies are shown at the end, walking over to that exact spot and still not being able to see any difference is super frustrating and ruins the fun in the long run.
Of course, anomaly games shouldn't be too easy, that goes without saying. But when you get the personal impression that it's becoming 'unfair'—like objects being shifted by just a few centimeters—it loses me. Or take another example: a cabinet in a white room. I walked around and didn't even see this cabinet or the room itself. I have no idea if I missed a room and didn't open all the doors, but like I said, that's just my opinion based on the current state of the demo.
The jump scares definitely hit the mark, though! ^^ Keep at it!
