+
+// 2. Gameplay - The player controls a paddle with the A/D keys. The player must keep hitting a moving ball with the paddle
+// to prevent it from hitting the bottom of the screen, which ends the gameplay and displays the game over screen. A timer is displayed on the
+// top left of the screen, indicating the player's score.
+
+// 3. Game Over - When the player fails at the gameplay, the game over screen is displayed, showing their time score. Player can then press A or D
+// to play again.
