No Music

[MooseTheScared]

Probably it would be nice as an option, but I would not use it. It would be too much for me to hear monster breathing behind and have no other warning than just the sound of footsteps, which the castle is full of. It would make the game scarier, but for me it's scary enough as it is. I'm on my second play-through, and, as lots of people already said, it's almost as terrifying and hard as the first time.
On the other hand, music helps to build up tension in frightening locations like the wine cellar or the refinery. Turning it off might take some of the horror away.
