Pipong is a simple clone of Pong game, the classic table tennis video game. It doesnt have much to offer, but it definitely is playable.
It needs a terminal size of 100x40 and two players, using ef and ok to move the paddles, but it feels more like left hand vs. right hand by the locations of the keys.
