Adding bits and bobs

While the enemies and weapon platforms are done for the demo, I figured I'd add some little features that add more life to the game.

The first feature is the destruction of weapon platforms. Initially, the platforms would just spawn a few explosions then delete itself. Boring. I then learned that the rigidbody has an explode method which is perfect for pushing the separate parts of the platform apart.

The other features are comets and asteroids which spawn outside of the level and fly through the system. It's highly unlikely that they'll hit anything important like a planet or resource station, but they'll do high damage if they hit.

This completes the work on the majority of the content for the demo. The last major component that's missing is the music and final boss.

Once the demo is released and I get some feedback, I can start working on new platforms, enemies, celestial objects, and more. Let me know what you think!
