Wow. Can you give us a clue what to do? I can line up objects (by moving the room around) so I can climb up to the key but I can't reach through the bars to get it.
Thanks so much for playing! We'll work on improving the clues in the game. You're definitely on the right track by aligning objects to climb, but you won't be able to get the key from the inside. Red arrows might point the way (:
