Buggy source:
private void updateGameOver(List<TouchEvent> touchEvents){
  int len=touchEvents.size();
  for (int i=0; i < len; i++) {

        if (Settings.soundEnabled)         Assets.click.play(1);
        ((AndroidGame)game).runOnUiThread(new Runnable(){
          @Override public void run(){
            final AlertDialog.Builder alert=new AlertDialog.Builder((MrMunchGame)game);

            int maxLength=5;

        if (Settings.soundEnabled)         Assets.click.play(1);
        if (world.score > Settings.highscores[4]) {
          ((AndroidGame)game).runOnUiThread(new Runnable(){
