A quick question. When I download new levels into the the Games\NumpyPhysics directory, what controls the order in which they are shown inside the program. Basically, how can I ensure that the tutorial levels appear first.

My 5 year old son loves this program, although he can only really cope with rolling balls down ramps. However, what really surprised me, was that my wife was itching to have a go. The last game I think she played was Grim Fandango ten years ago.
