Adding fog walls to prevent progression until a mini-boss is beaten kinda sucks. I loved how open everything seemed in previous demos, with the game really encouraging you to use every possible tactic, including evasion if you wanted to save a tough enemy for later and sneak past them.
Between this and the lame change to the Headless enemy, I hope From doesn't second-guess themselves anymore before next weekend.
The fog wall looks...weird and out of place in the game and the placement over the previously reachable hole in the wall looks bizarre.
