Cool idea! It is generally quite spooky.
I guess it is a bit easy because the "anomalies" are drawn in a much sharper resolution than the background. So you are just looking for objects that are sharper than the rest of the game. Or maybe it's because I'm on a 1440p monitor? Not sure.
I was honestly expecting a jumpscare at any moment, and I'm kind of glad it didn't happen.
Except of course this wonderful chad at the end. I like him
