Thanks so much.
We considered writing music for it, and Enjaku found some legally-usable pre-made stuff that would have worked well... I ended up not adding it in simply because I was afraid of causing a catastrophic error in my coding, after spending an hour tracking down a missing semi-colon (not exactly unusual in programming, yea?) to get the game working again on Sunday evening. "It's working. It's stable. I'm exporting it and putting it online before something else goes wrong." :D
Thanks again for taking a look :)
