Brick Break

Players can set custom key bindings and sound options.

PowerUp drops are random.

As game progresses, game difficulty increases and randomly varies between:  faster left-right speed, faster up-down speed, faster spawn rate, and smaller blocks.

I recommend saving the penetration shots till late-game.

The game will store your high score and key bindings on the local machine. This means that the information will be saved regardless of you closing the web browser or restarting the machine, however, if you play the game on a different machine, then you will not have the same bindings/high score.
