This program differed from Unit 1 programs because

it felt more foreign, if that makes sense. The code used in this program
was not my work hence, I did not feel as though I completely understood how
each agent was doing what it was doing. I guess I can see the value of
agents because they really do cut things short and functional. But I much
prefer the labs and programs that had more original input for the learning
experience! At this stage I don't know if I am comfortable or confident going
into the game project but I will try to think more about the agents
to understand better.
