So far, what they did in Patch 3 was a great improvement in my opinion. I like how they redesigned Quentin's office and I like the Cassette puzzle so far too.
However, there are some things which I didn't like, like how bright Quentin's office is in Nightmare 1 and the realistic looking potholes. Those are just a few things I listed because I could make this thing longer.
I'd like to see more of these puzzles (referring to the post game) in the future too. Along with some lighting adjustments and a slightly spookier theme too.
