Some more notes on blender. Scaling and dimensions seem to have a strange relationship. To actually modify the dimensions of an object bring up the transform properties ('N') and then press CTRL-A to apply the magic once your done. Weird.
I also revisited the best of global game jam after a gamasutra article on the jam and to my very surprise, zeppelin escape got a comment of being a good game, and when i checked out the leaderboard, were the 10th best game! wow!
