Potential Enhancements

The images were left pretty basic on purpose. This is probably the easiest way to spruce up the game.

Many breakout style games have special bricks that change the gameplay temporarily.

Add more bricks, and draw a picture. Might go better with a bigger playing area.

Gears lets you store data locally in a database. No internet connection required.

In which case you'd just move the paddle to a new mouse position on every tick, and track the difference in paddle.dx for the friction effect.
