Paddle Ball V1 (Python)

Do you remember Alleyway from the Nintendo Gameboy? It was a 2D game where the player moved a paddle on the bottom of the screen whilst a ball bounced around the screen. If the ball hit the paddle it would rebound upwards, if the ball touched the bottom of the screen the game would end.

Alleyway was based/very similar to Breakout and Arkanoid , but it was the game that introduced me to that particular genre. After watching Ready Player One recently I got the urge to re-check out some of the games of my youth; and this soon lead me to thinking that some of them might be easy to remake in Python. This version contains a basic title screen, paddle and ball and a basic ending screen.
