That's a great update, I like the new ai (even if she's even more violent than before).
I found a little bug when she's chasing you around a corner, she will pass through it almost a meter before the corner, don't know if it's just me. Also on Easy mode, the character starts without shoes but isn't harmed by the glass, sometimes they magically appear on him.(still didn't figure why it does that)
As someone else pointed, the lack of ways to break the line of sight makes the game terribly difficult, but I really like what you've done on the new layout.
I'm looking forward to the new game modes, keep up the good work. ^^
Edit: I don't know if it's just me, but I still find games where I can't get the keys for the last 2doors, Is it possible that their keys spawn within each other?
