clue feedback

I have been having people try and figure out some of my clue types, the word wheel has needed the most explanation of how it works. and is the one that the fewest people have successfully deciphered when there are only two words to figure out, so having phrase that is deciphered using it is out of the question.  Also some people didn't figure out that the braille was braille, a suggested solution was to print it in braille so that the players don't only see it they feel it.
