This is completely different than anything we did in unit 1. When creating the nav game all the code feels connected as the code was broken up into asteroid, asteroid spawner, game, and spaceship. I think this is so much easier to follow as it was easy to figure out what each thing did. Also, this uses classes which we did not use in unit 1.
