Hiii I have questions when I going to bed the then why is there fog or something like that what is it
It's for dream sequences.
Dream sequences are scenes commissioned by patrons in our $20 tier during our first two years of development. This was offered, no cost to us, by our lead writer at the time.
Because of this dream scenes will not be given CG Scenes. However, if you'd like to commission an outside artist to make a CG Scene for a particular Dream Sequence then I'll have no issue adding it into the game as long as the credit to the artist is on the image itself.
I've offered this alternative dozens of times over the past few years and no one has done it. Go figure.
