I've encountered clever and creative puzzles, this is just not it for me. Personally, I make the distinction that good, creative puzzles do not rely on confusion. One example, opening that door, we can have: B interpreted as 8, L as inverted 7, W as rotated 3, M as another rotated 3, E as reflected 3, b as inverted 9, q as 9 and so on. It's trivially easy to make a puzzle based on that but it's not really clever or creative. Remove the tricks and the puzzles end up being trivially easy.
