Use [up] and [down] arrow to control your pad. Don't let the ball slip on your side of the field. Gray part of your pad will decrease in size every time you lose a point and the green part of your pad will gain every time you win a point. Good luck and have fun. Hit the ball with the green part will execute a speed boost.
New update: I've compressed the sounds as much as possible, which reduced its size down to 2.38MB
Thanks for the comments :) Also, please let me know the highest level you've reached. This will help me fine tune the difficulties for future developments.
Internet Explore glitches: If you use IE8, you will encounter many glitches. For example, the paddles will fall apart and the ball will get stuck.
