You are a paddle. You can move up and down to block the ball.
Making interactive fiction of Pong is a wacky idea that Granade manages to transform into a weird experience, thanks to a writing that is reminiscent, in ways, of the language in For a Change, only more convoluted and presented as a kind of inner monologue of the paddle’s. Some feat, really, since (though there are appropriate responses to other standard commands) the paddle can (did I mention that?) do nothing but move up and down. The novelty of the writing is, however, gone some while before either you or the opponent Non-Player Paddle scores a fifteenth time and the game is at last over.
To anyone who never played or even watched a match of Pong, this game must be terribly confusing; and I suppose it would be quite the worst introduction to interactive fiction that could well be imagined.
