v0.5.0: Silent falls build

The first playable build of Harmony Falls came together over the past 24 hours. This included:

• Setting up the controls.
• Hooking them up with player movement and shooting mechanics.
• Spawning endless falling enemies.
• Checking for enemy and projectile collisions.
• Generating random color schemes.
• Drawing them all to the screen.
• Adding particle effects to interesting events.

This is a good foundation for the first demo. My goal for tomorrow is to implement all the sounds. This includes musical cues for enemy positions, projectile, and collision sounds.

Enjoy!
