You can't get it past the other guy, who'll knock it back to you at a slightly different angle, but instead touching the ball to get more points. It gets progressively faster, too!
Up and Down arrows to control. Note that you can't change the angle of the ball, but your opponent often will.

I've tried to get it so that the ball doesn't go within a certain range of vertical, too, so hopefully that'll work.

Music is a take on Din Da Da that I came up with earlier today on a whim.
