This cannot be just me but this game is so dark. There are no options for gamma, no flashlight, no vision. I saw a sliver of light under a door and tried to push on it, I heard the door creak yet it does not allow me to proceed. Is this a bug or what?

It needs a save game or checkpoints, I've reached the RED chase area but had to stop when I returned i'm back at beginning which is a bit much, I've lost progress!

we tend to play the backroom style games as a group so its a real shame this one isn't coop.
