This code is very different from Unit 1. Unit 1 was very top to bottom. This is more object driven. Instead of one loop or code there are agents that act to put everything together as a focus of what agent should be doing for the game to become a game such as the spaceship, asteroid, asteroid spawner are all used to generate the game. This code seems so real and more day to day life in my opinion.
