Very spooky! I admit that I was kinda stuck at the very beginning since I didn't know what I was supposed to take pictures of. I just knew that if I took pictures of certain things I would get a sound cue. I assume I was supposed to follow the light trail that appeared in some of the pictures?
Anyways, I eventually got to the part where the floor started filling up with water and that was my favorite part. It felt very tense getting chased by the ghost guy while trying to move forward. Actually I got jumpscared a few times by the ghost!
I think y'all nailed the atmosphere. My only feedback would be to make it a little more clear what the player is supposed to take pictures of, since I was randomly taking pictures of anything that looked interesting. But overall this was spooky and enjoyable!
