I was one of the people who played the initial versions; don't get me wrong, they did have places where it was excessively dark. But MAN, was it scary! The hallways feel a lot less creepy now because all of them are well-lit. The creepy atmosphere would at least benefit to having the lights dimmed or flickering (some of the lights could even be straight up turned off).

Remember when the "glass room" was this dark, and you first saw the silhouette of 173 deep in the back? http://static.taigame.org/game_screensh ... each-8.jpg

My monitors brightness settings don't stay the same for more than an hour
My SCP brightness is so dark I can never see a meter away.

That is the case for a lot of the facility, but I feel that the hallways are too bright and for me act as "breaks" from the horror. Why give players breaks, keep them crapping their pants

From what I can tell, Light containment is -Fairly- lit, Heavy containment is -Dark-, and the entrance zone/office is Well-Lit because the SCPs are more behind us, Now it's the MTF.
