Can't restart a level

I tried Scene$$anonymous$$anager.LoadScene ("OtherSceneName", LoadScene$$anonymous$$ode.Single); and t's still the same. Before I press R my scena looks like this: http://oi63.tinypic.com/20jo57d.jpg And after http://oi64.tinypic.com/fc91n7.jpg

And my code goes like this:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.Scene$$anonymous$$anagement;
 
 public class Controller : $$anonymous$$onoBehaviour {
     public GUIText scoreText;
     public int score;
     public GUIText restartText;
     public GUIText gameOverText;
     public GUIText countTargetText;
 
     public GameObject target;
     private float nextDrop = 0f;
     private float dropInterval = 2f;
     private float changeInterval = 5f;
 
     private bool gameOver;
     
 
     GameObject[] countTarget;
 
     void Start()
     {
         score = 0;
         UpdateScore();
         gameOver = false;
         UpdateScore();
         restartText.text = "";
         gameOverText.text = "";
         countTargetText.text = "0/10";
         InvokeRepeating("Target", 1, nextDrop);
 
 
     }
 
     void Target()
     {
         float x = Random.Range(-26f, 26f);
         float z = Random.Range(-22f, 27f);
         Instantiate(target, new Vector3(x, 0, z), Quaternion.identity);
     }
 
     void Update()
     {
         if (Time.time >= nextDrop) //If ready to spawn
         {
             Target();
             nextDrop += dropInterval; //Set next spawn time
             if (Time.time >= changeInterval) //If ready to change spawn interval
             {
                 if (dropInterval > 0.5f) //Change spawn interval to 3/4ths what it was
                     dropInterval *= 0.80f;
                 else //$$anonymous$$ake sure dropInterval stays above 1.
                     dropInterval = 0.5f;
             }
         }
 
         countTarget = GameObject.FindGameObjectsWithTag("Target");
         countTargetText.text = countTarget.Length + "/10";
 
         
             
         
 
         if (countTarget.Length >= 10)
         {
             gameOverText.text = "Game Over!";
             gameOver = true;
         }
         if (gameOver)
         {
             restartText.text = "Naciśnij R żeby zrestartować";
             if (Input.Get$$anonymous$$eyDown($$anonymous$$eyCode.R))
             {
                 Scene$$anonymous$$anager.LoadScene("$$anonymous$$inigra", LoadScene$$anonymous$$ode.Single);
 
             }
         }
     }
 
     public void AddScore(int newScoreValue)
     {
         score += newScoreValue;
         UpdateScore();
     }
 
 
     void UpdateScore()
     {
         scoreText.text = "Punkty: " + score;
     }
 
 }

Any idea how to fix this? I stuck with this problem for several hours now I I'm out of idea.

I spend two days trying diffrent things and still nothing works. It's very strange. It look like after reloding only player position is restarted nothing else. I also don't understand why CancelInvoke(); does not work. Also after restarting displayed colors are difrent as you can see on screen shots Before and After. This is small game so I even tried to make new project and make it again (with the same code) and still nothing. I'm really desperate, I'm afraid to start any bigger procjets without solving this problem.

I honestly don´t, have you tried to play around with Scene$$anonymous$$anager ? Like UnloadScene for example, then load it again ?
