what happened to key I picked up? and the zero? Also saw clues? that I should have written down as they are gone after I look at them. I

have 1 through 8, saw key but didn't touch it - so it is still there. need 9? didn't touch the zero or O and it is still there.

I drew one pic but not sure how to use it.
Silly me - mid-afternoon droop - have them but up high in inventory that was out of view. Have 14 things now.
