I’ve only played a few anomaly games before, and this is definitely one of the best of them. The backrooms theme has a good expectation for the style and I think you did a really good job pulling that off. There were a times I’d wander past something and question whether it had been there the whole time (it usually had). I thought the anomalies that I caught were good overall, sometimes a little hard since I’d fail but that’s just the game.
Like Collectonian suggested, subtitles would’ve been nice! Somehow the audio got set to 0% so I missed all the talking in my first attempt (~20 minutes) and wasn’t able to get that far again. The talking adds a lot to the game so it was a shame to miss it at first. But overall the dialogue added a lot and made the repetition a bit more interesting.
Also since I was playing on a tv, some of the text was hard to read on a few of the props. A larger calendar might make that easier to read, and an outline or different styling to the number on the computer screen would make it easier to read at a distance. Fun game overall!
