         {
 
 
             if (PlayerPrefs.HasKey("FINAL_SCORE" + i))
             {
                 string[] scoreFormat = PlayerPrefs.GetString("FINAL_SCORE" + i).Split(new string[] { separator }, StringSplitOptions.RemoveEmptyEntries);
                 playerScores.Add(new playerScore(scoreFormat[0], int.Parse(scoreFormat[1])));

             return;
         }
         playerScores.Add(new playerScore(name, score));
         playerScores = playerScores.OrderByDescending(o => o.PlayerScore).ToList();
 
         for (int i = 0; i <highScoreManager.scoreCount; i++)
         {
             if (i >= playerScores.Count) { break; }
             PlayerPrefs.SetString("FINAL_SCORE" + i, playerScores[i].GetFormat());
