Very surprised to see so little ratings - your game deserves so much more attention.
It's a very unique and harrowing horror game and absolutely nails the theme. It's a very subtle creeping kind of horror, I don't know how to explain it in words but it's extremely well executed.
I think this is probably the best game in this jam; it's not my favourite, but personal preferences aside and in terms of sheer quality, it is ludicrously good and one could say peerless.
To make it a mixed constructive review, I feel the ending is a little abrupt but that's understandable given the time constraints of the jam.
Also it does tend to chug a bit in some parts and I'm guessing it's probably the filter or a combination of that and the image files being processed at the same time. Not your fault, but it does slightly break the immersion; though only slightly.
Other than those small critiques I'd say as a game, excellent job. For a game made for a 9 day game jam, I'd say excellently excellent job.
