And our last line of defense is the lone pilot fighting against their numbers.

This, this was REALLY fun to make.
Yes, the barriers are a MASSIVE cop out. I was gonna make them look like space rocks, but it looked like poo, literally...
But everything else is great. The UFO, I just went with a basic UFO look.
The top aliens, were okay, the bottom ones, interesting, but the middle ones, oh the middle ones. That was were I started, and they look AWESOME to me.
And even the ship, I had to turn that very basic sprite into something, while adhearing to the shape, so long wings did it.
