- Now that the quaternion problem is solved, I've had time to take a breather and return to some existing elements of the game that needed attention. For instance:

- Increased asteroid size by a factor of 4+. This makes them easier to hit, but also tougher to avoid. In general I find that it makes the asteroids more a part of the game when they are bigger.

- New enemy ship graphics (I added enhancements to a free model I downloaded from TurboSquid.com)

- New ChaseCam view allows more panoramic view around the ship

- Revised the particle systems routines to make the particles move more realistically

- I found that the less text I render, the better. There was a dramatic speed improvement when I removed the debugging text.

- Created a basic framework for powerups - a few of the smallest asteroids are of a slightly different colour, and will release a random powerup when hit. (Coming soon!)

- More combing of old code and fixing little errors

- Experimented with temporary gravity toward the -z wall (this could be a powerup)
