title: Restart game XNA
body: <p>How can I make a game to restart when I lose? My game is structured in 3 parts: mainMenu,Game and the end (when you lose). So I divided the Update and draw method in 3 parts. Now I need the option to restart the game if I lose.</p>
  
  <pre><code>bool lost=false; //when it is "true" I lost
  if(lost==true)
  {
      if(Keyboard.GetState().IsKeyDown(Keys.Enter))
      {
      // Restart game
      }
  }
  </code></pre>
