I have mixed feelings about this game.
On one hand, the game is ridiculously difficult because the clues are very obtuse and the game is expecting a single specific answer to each puzzle when other potential answers exist. I never would have guessed some of these answers. At least one puzzle appears to be broken for me since I couldn't connect to the wikimapia site to load the clue. That said, I'm a casual player (not an expert puzzle solver), and this game might not have been designed for my skill level.
On the other hand, the puzzles are usually very novel (new to me) and clever. Once I know the answer, the clue usually makes sense, and makes me smile, and makes me interested in what the next puzzle will be. I just wish the leap from the clue to solution were as reasonable as the leap from the solution to the clue. Players who get stuck on an earlier puzzle are missing out on some pretty cool puzzles and fourth-wall-breaking experiences later in the deck.
You've got some really cool ideas here, though it feels like the difficulty might need to be tuned with more play-testing. For example, maybe accept alternative answers, and/or re-order the puzzles so the easier puzzles appear sooner.
