This game is a true 3D pong game. While in 2D pong you move your paddle left and right you are now moving it fully in 3D. At the first its quite hard to figure out the position of the ball but after a few minutes of practice you will get more skillfull.
To control pong 3d you need to mouse the mouse towards the ball, when you get a little more skillfull the game becomes a lot more funny to play.
