Lots of little improvements

Now that we've had some time away from the pressures of Ludum Dare, we've made a bunch of changes to make the game more fun and enjoyable. For example:

• Now there's a pause screen where you can change the volumes of music and sound effects
• High score + saving!
• The breakout mechanics are a bit more fun
• The ball no longer freaks out QUITE as much
• Pieces are colored and shuffled correctly per the Tetris™ standard

Of course the jam versions are still downloadable from the game page!
