Time for action – tracking player restarts

Let's create a method to update playerDeaths to see the method arguments that are being passed by reference in action.

Open up Utilities and add the following code:

 public static class Utilities

     public static bool RestartLevel(int sceneIndex) 
     {
         // ... No changes needed ...
     }
 }

Let's break down the code:
