Expanded Region Shaders!

So, after getting the fractal Brownian cloud to work, I kept working. I added a tunnel-like shader to the second region, and for the third, I have derived a method of hue-rotation and fed it through a factor determined by a Brownian cloud. They both have sweet unique looks now.

I've also determined that the game is getting a little too difficult even for my tastes; so soon enough I'll likely add hit points, but that hasn't happened yet. I've got a few assets waiting in the background. Some days I'm an absolute god with shootemups, some days I'm a turtle flipped on its back. I'm thinking the rate of fire of some of the enemies needs to be tuned down a bit, too.

Everybody have fun with the new art!
