Thanks, glad you like it! Yeah the mobile web version is experimental, I just added the touch controls so people can at least try it. The next update won't have anything web mobile specific, but I have made a big change to note spawning so the notes shouldn't bug out and start spawning in the box at least! This was a issue that could happen on any lower powered device (e.g. chromebooks), but it often affects mobile since they're less powerful too
