Curveball

http://www.albinoblacksheep.com/flash/curveball.php
Curveball is a very entertaining “pong-clone” type of game. The principle is the same; try to bounce the ball into the goal behind your enemy, while at the same time defending your own goal. The most obvious difference from the original pong is that now you have another dimension to move in, you can move up, down, left or right. The enemy is also now in front of you, instead of to the side. The trick is to try to curve the ball so that your enemy wont be able to catch it, hence the name “Curveball”. You will receive bonus points if you manage to curve the ball a lot, or hitting the very center of your paddle. The paddle is now also controlled by your mouse, instead of the usual keyboard arrows.
