You are using Player Prefs to save the score value and then are setting score to it when you start the game. If you want the score to start at 0 every time the game starts then you have no need to use Player Prefs.

Well in the start method you set the “Score” to 0 and then already save it as the new playerPrefs Score, thats why it’s always the same. Then when you update the score you have to set it again in PlayerPrefs

Under IncrementScore(); you have to set the new score to the playerprefs:

  if (Scores > PlayerPrefs.GetInt ("ScoreText")) {
                 //IncrementScore ();
                  PlayerPrefs.SetInt ("ScoreText", Scores);
             }
