Version 2

Bug fixes: Fixed a bug where the enemy would hog the ball leaving the game at a stale mate

Thank you for reporting! The enemy would sometimes catch the ball in the corner (either top or bottom) and then get stuck on it.
The game could no longer be continued.

New Features: Added a speed boost to the enemy every time the player scores 

The game should now be a bit more challenging because the enemy gets slightly more responsive every time the player scores. Before there would be about 5-6 bounces per point, I counted between 10 and 16 now.
