Time for action – creating a static class

Let's create a new class to hold some of our future methods that deal with raw computations or repeated logic that doesn't depend on the gameplay:

1. Create a new C# script in the Scripts folder and name it Utilities.
2. Open it up and add the following code:

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;

 // 1
 using UnityEngine.SceneManagement;
 
 // 2
 public static class Utilities 
 {
     // 3
     public static int playerDeaths = 0;

     // 4
     public static void RestartLevel()
     {
         SceneManager.LoadScene(0);
         Time.timeScale = 1.0f;
     }
 } 

3. Delete RestartLevel() from GameBehavior and modify the OnGUI() method with the following code:

  void OnGUI()
  {
      // ... No other changes needed ...
 
      if (showWinScreen)
      {
          if (GUI.Button(new Rect(Screen.width/2 - 100, 
          Screen.height/2 - 50, 200, 100), "YOU WON!"))
          {
              // 5
 ...
