We also question whether the player likes the puzzle, or if they think it is relevant to the game and story. From here we work on fixing the problem areas, making it clearer, adjusting the difficulty, and enhancing the experience. There is a lot that goes into puzzle creation, and it takes people from every department to make it happen beautifully.
Speaking of puzzles, I must have created a toughie of a weekend puzzle, but luckily not too tough, because a couple of you have solved it! Hooray! One answer that I saw on the message boards was correct, yet the solution wasn't mentioned. I think I will hold off one more day from giving the solution so you can keep trying. ;)
