Really enjoyed playing! Very hard at first since you're comparing literally pixels, haha. But that's exactly what I was looking for. :)
Some feedback from my side: It would be great to see a list of the locations you've missed anomalies on the game over screen. This would help memorising the location and anomalies quicker.
And another aspect that might be cool: Anomalies that already occurred once can't occur another time in the same playthrough. This adds a bit more variety and as a result more horror (plus I like checking off anomalies in my head :D)
