FINALLY got round to finishing this. Some of the best level design I've seen in a game, There's so many ways to go about every stage but never a simple way to cheese it. The fun really comes from playing around in the levels you've already finished.

My only real complaints are that the best two stages are the first two with the penultimate (Colorado) being least fun. The overall story is weak too, but it's not really what I was playing for.
