I had the same 'class loading problem' but i believe we can easily overcome it. Just save the main file (the very first one you know :P) with any name in the same folder where we saved 'ship.as' file. doh
Awesome game! so much addictive, can play it all year long continously =D the concept is really nice... the timing of the pizza and the baking things are uber cool. thanks for a game like this! always wanted to play such games via this stupid pc of mine
