Whoa awesome, I'll pass that on! The music is by Pete Ellison of Diskowarp Records, he plans to release the soundtrack once the game is finished.
For now, you can grab the .OGG files from the source code repository if you want to add them to your music library.

If you click each .OGG file it should take you to a page with a download button in the upper-right corner.

Sorry this is so cumbersome! I really need to work faster to finish the game so Pete can release an official soundtrack 😅
