If you open the APK file with a ZIP manager (for instance by changing the .apk
extension into .zip
) you’ll find the music into assets/game.mp3
.
But maybe should you first ask the author if you can remix his music? (I don’t know how those copyright stuffs work.)
If for some reason you can't get the the apk, look at the Soundtrack page. (I have no idea if it's possible to download it from there)
Now that watabou's released the source on GitHub, you can actually get it from there (under assets). In addition, because Evan also uploaded the source for Shattered Pixel Dungeon on GitHub, you can also get it from there as well.
