The above video shows all of the additions that I've made since last post. Now, the game's got actual levels, with two new enemies. Well, new enemies in a very rudimentary form, anyway. Still no actual assets, but I'll probably work on that next.

Probably the most difficult thing from the past week or so was figuring out how to handle the different levels. Making the levels themselves was the easy part, since they're basically just data for the enemies they have and a unique identifier for that specific level, but I wasn't sure how to best handle the IDs and having the game know what level to go to next, especially since there's going to be different worlds.

Luckily, I've settled on a solution I'm pretty satisfied with, so all of this level business shouldn't be an issue going forward.
