Put this together based on another project (https://github.com/PROGRAM-IX/vectorwars). No sprites used whatsoever, all content is generated procedurally and drawn every frame. I love this kind of game, but thought it might be a little heavy for PICO-8. Apparently not, at least in this small version. I'll probably play more with this for other more complex games.
