For this lesson, we will show you how to add a winning screen to your game for when your players get to 2048. The win screen will give the players the option to restart or continue. If the players restart it will reload the scene. If the players click the continue it will hide the win screen and as a result, the players will be able to keep playing the game to get a higher score.
