Starting work on the audio system
The music, graciously provided by Vinzent Spielmann and Hannah Matthay, is divided into tracks. From there on I can separately adjust each track's volume, to fade them in and out at will and create the mood I'm after. This will be able to happen programmatically, using the same node-based trees as the game logic uses. The way that I'm keeping each track synced up is by, as a song in playing, always having all tracks play at all times, and only muting the volume is I want one
