[NO Spoilers] How to dare...?

I'd assume the easiest way to take the edge off is to turn up the gamma until the darkness doesn't bother you anymore, or turn down the (really well done) audio or play yakety sax over it.

Unnecessary to mention that this destroys the intended atmosphere of the game, but hey, if it helps you play longer than 10 minutes, that shouldn't stop you.
