Background music update

Looking back at this, it felt appropriate to have some kind of music come in during the first big transition, to emphasize that moment and reinforce the mood. With a little looking, I found candle's UI for David Mowatt's bitsymuse hack, so all I really needed to make it happen was a piece of music.

I did consider finding a bit of royalty-free music to suit the mood - I only know how to make music in PICO-8 so far, or I guess by singing? - but then I decided to write my own anyway.

I didn't go into it with terribly much in the way of a plan, but I did want a bit of a strummy-guitar feeling to start with, so I grabbed the custom SFX instrument from a past composition with that vibe, tweaked it a little, and started from there. (The strums are a little less harsh in this than that - it just felt better that way with the notes I was putting down.) After I got a strummy guitar part that I liked, I ended up bringing in the PICO-8 organ instrument to do a more lyrical line, that then ended up having some harmonies in it.

And then I brought the energy back down so it could loop.

It's kind of actually significantly longer than the Bitsy story needs, but I hope it feels good.
