Worst part?

Ah yeah...Choir would be much more daunting without the ability to tell where the sounds are coming from. I played that part with headphones.

Agreed on the waterlurker part. That section was really intense for me and probably retains its intensity for me during reruns more than any other part. It was a different type of intensity though. More like panic than dreadful fear like most of the game.
