Just any sort of note/review. When I went to the puzzle portion of the demo, I am glad it did not force me to complete it, even though I failed once once on it. Sort of strange, but still glad I was able to continue the story as normal. Might be nice to have the puzzles available in the main menu after players unlock them during the game if they want to try to play it for "fun", I'm just not the biggest fan of certain puzzles...
