Sorry, but by accident, when I was creating chamber 2 from chamber 1, I clicked "save" instead of "save as", and it somehow deleted chamber 1 on the workshop, replacing it with chamber 2. So there are some comments which were meant for chamber 1 but are for chamber 2. I feel sorry for this, but I can't do anything about it now. Still, have lots of fun with this one, even though it's so easy.
