It's recycle. Bullets properly recycle. It... It is underwhelming. Technical progress will do that, I guess.
That got me thinking. Do I really need to re-do enemy pathing? All it will do is give me more discrete control over the power of any given wave of enemies. While that is really, really important, is it more important than, say, boss battles? Character interaction? Factions? All of these things are major components, and fiddling about with what I already have complete (to a moderately acceptable degree,) is only going to slow further progress.
So what I'm going to do, before anything else, is clear my mind by making some explosion graphics and getting ships to explode. Because explosions. I'm sure there's some word that starts with R that could tie this back together. Rexplosions.
