Tonight, I did some refactoring, cleaning up from the slapped-together job that was the shooty code.
Took a page out of the books of some of the demo programs and reduced all of my game objects to 'actors' of varying specificity. This let me build draw and update callback functions into the tables of each actor, and majorly simplified the process of calling them. Additionally, things are now nice and generic for when I move on to adding more
Next up will be adding an enemy type that just tries to chase the player around. Look out!
