Ah, nostalgia. I remember back in the days of surfing through AddictingGames.com there was a game called CurveBall. In what must have been cutting-edge coding at the time, you were put in control of a 3D pong paddle which could influence the way a ball was shot by moving the paddle as they made contact. It was pretty much a high-tech version of tennis, and was pretty kick-ass.
Deflecticon is a game that's similar to CurveBall (it's even mentioned in the description), only instead of using your mouse, you use your finger on your smartphone or tablet.
