Pong Game Shorter Version

This is a simpler version of pong which is one of the first computer games ever created. This simple version features only one bat and a ball. The game will have a controllable bat at the bottom of the screen and a ball that starts at the top and bounces around off of all four "walls". When the ball hits the bottom the player loses a life and when the ball hits the bat the player gets a point. The player will start with 3 lives.
