Johnnycowgirl, I also picked the paper to sign and went to sign it with the feather which I figured was to be used as a quill. Didn't seem to work so I picked the collar. The whole time working thru those answers she keeps wondering if the distructive action the ghosts say she's causing/choosing are real and is she dreaming. Got thru the ghost test and met the 'bad guy' who wants the crystal she gave him earlier so she has to find a substitute in a pile of crystals. I'm down to one crystal and can't find it. I ask for a hint which tells me 'there's nothing new here'. There's seems to be a crystal under a helmet visor but it won't stay open.
BFG doesn't offer a WT and the form, tho the same crystal question is posted and viewed by quite a few people, no answers. Gamezebo's WT gives detailed instructions about picking the crystals out of the jewel pile. It says to pick all the crystals without opening or moving anything. Then open the 2 chests, move the left arm and open the visor. I did it randomly opening and moving items along the way. Now the visor won't stay open.
From what I've read I'm very close to the end of the game so any help would be great!
