Very interesting concept, somewhat of a different take on the Fatal Frame idea. Trying to find entities using a camera and locating them entirely by the noise they make was really interesting and I quite liked it.
I'd have the scrollwheel be what allows you to look through your pictures, I feel like that'd be a lot more comfortable. It'd also be nice if the images wrapped around, so once you got to the last image it'd loop back to the first if you tried to go up and vice-versa.
It also felt like it was kinda random when the entities would kill/capture me. I could hear them growling, but they seemed to growl regardless. Maybe make them make a distinct shriek / screech right as they're about to pounce so you know to try and GTFO.
Also ghost van lol.
Overall I think this has a lot of promise if you want to try and take a month or so to really polish it up and expand on it! Otherwise, good job on your first game!
