The Music Release

This latest version adds some ambient music.

 I like using music-like sound effects, particularly in abstract games like this one. But that makes adding a soundtrack difficult, as the sound effects tend to either clash with the music, or get lost in the music. 

The clashing is a music problem that you can solve musically. 

The getting-lost problem is different. In the past I've addressed this is with extreme equalization, trying to give music and sound effects their own separate ranges of audio frequencies. That sort of works, but it's limiting and often led me to infinite-seemingly loops of redesigning sounds to stay out of each others' ways. 

Here I've addressed it with having the music duck its volume when it "hears" a sound effect. When the sound effect level drops below a certain level, the music volume gradually ramps back up to full volume. (Effectively a sidechain compressor in code, if you’re an audio production person.) This is much more effective and much less obvious to the listener than I expected. New trick acquired!
