The PNG ghost was 2spooky4me (I'm not good with 3D horror ;_;). The art quality was amazing. I especially like how seamlessly you mixed 2D with 3D. I didn't even realize the hands were 2D at first.
As for the gameplay, I felt like the signs on the doors weren't very clear about what they meant or whether they even mattered. In my playthrough, almost every door had a maximum danger sign on it. Admittedly, this added to the fear factor, but it also made me feel like my decisions didn't matter and it was all just RNG.
That said, very polished game for something made in just 7 days. Awesome stuff!
