This is a fairly simple game of pong made out of 93 command blocks.

Important notes:
Not multiplayer friendly.

I found it a bit difficult to play, but you can edit the command blocks that have the gold pressure plates on them to change the speed of the paddle or ball. (The higher the Timer score, the slower they'll go)

Game ends if you hit all the black, gray, and silver blocks or the ball touches the bottom of the window.
