The two IT guys at my job are named Sean and James, and they recommended this course to me. So I dedicated my first game to them.
I mistook the first time the lecture said “Go ahead and make your own story” as “Go ahead and try to make a whole game without watching any more videos.”
I wound up using int variables to determine whether the player had picked up certain items, rather than using a whole new state. But after I continued on, I re-did some code, and added the other room states.
