I updated the Mobile.js file so that that music will actually play on iPhone. I have tested it on several and the music now plays.

The music already worked on Android/Samsung/Google.

This game has music made for each level by Alexbit, also there is an intro, win loss etc.. so I really think it helps give the best experience of the game having the sound effects and music. 

I hope this makes the mobile experience even better.

you still need to tap the screen/expand for the music to start playing so you don't have music blast unintendid..

the code is from nekobungi commented on Jul 24 2020/1 on github I think.

1. Open the exported folder after "Export Web" is done

2. Open js/other/mobile.js with any text editor

3. Comment-out the following lines: line 91, 95, 100, 101, 102, 103, 104, 105

// window.audioContext.resume().then(() => {
        settings[0] = true;
        gameboy.initSound();
        soundReady = true;
      // });
    }
  }
}
// var soundInitTimer = setInterval(function() {
//   if (GameBoyEmulatorInitialized()) {
//     initSound();
//     clearTimeout(soundInitTimer);
//   }
// }, 16);
