[EDIT] I put the soundtrack back for Windows. The last version I tested played pretty fine in Windows 10, so you guys shouldn't have a problem with it.
I've been warned that the Windows exports are having problems with the audio sounding accelerated and broken. I'm trying to work around it, but so far I didn't manage to make Godot's stream player work fine on my testing environment.
For the time being, the Windows binaries are replaced by versions without the soundtrack. It's painful to do that when I've worked so hard on the music, but it's better than making the players listen to an earrape version of it.
