I like how accurate the audio is! Honestly I found the wall hack more often than not didn't do anything, and mostly relied on the audio and distance to monster to determine where he is to avoid him.
Being faster than the monster also was strange, because unless you were in a room you could take a couple quick turns and get away no problem. The things I had to pick up were also kind of hard to see a lot of the time.
The atmosphere/graphics were overall really cool.
