In this vid we'll look at making the backbone to a working game. In the end it looks exactly the same as last time, but we've now got a way to switch between screens or levels and load and unload resources.
I've been a little reckless with the GameController. At the moment, it changes levels and it deletes the object that calls it before that object has finished running its method. We have to be careful not to do anything after the GameController returns from a call to SwitchLevel. The alternative, and safer thing to do would be to add a "Closing" switch to each level. When the game controller sees that a level is Closing, it could delete the object at a safer time (i.e. not when it's halfway through a method). We might change it in the future if I remember.
Also, calling it a "Singleton" is a little strange, we don't actually make any objects from it. Perhaps "static class" would be a better term.
