Thanks for the feedback on the game! I'm glad you shared your criticisms. The game can't grow without it.
As far as the fog goes, if you look in document iv you'll notice that the fog is a red tint when subject 1 is in 860-1. There are some original things that I have changed, (like the monster, which is never visually described beyond a paw, and audio was never described past a roar. [I realize this roar that is currently in game is not ideal, and will be replaced later]) but overall the final version of the game will MOSTLY adhear to the Foundation Wiki for those 4 explorations. There will be some changes I make for creative control. (SCP containment breach did this as well) But the goal is to more adhear to the documents for the demo. Thanks again for your feedback and I'll definitely be taking it all into consideration for the future of the demo and the final game as it takes shape.
