Off-topic: I think they should remove the ability to unlock worlds in any order. Main reason being, difficulty. You can't go from Ancient Egypt to Big Wave Beach and expect things to go all hunky-dorey. That mechanic would make sense if the worlds were all the same difficulty, but they aren't. The game is designed for you to play the worlds in order, and the worlds increase in difficulty. Thus, popcap really, really should just remove that mechanic and make it so World Keys unlock the next chronological world.
