W+S control the left paddle; up and down arrow keys control the right paddle. If you hit the blue block in the centre, the ball will head towards the blue side. If you hit the red block, the ball will head towards the red side. :) As always, if the ball touches either of the large blue or red bars, that team will get one point.
My issue in this rendition was that the ball would get stuck too easily, continually bouncing back and forth between the paddles without changing directions. So I added a new twist to it to see if it helped the problem. What do you think? Comment below. :)
