It's just Pong. There's no intelligence to it, it's just an abstracted match of ping-pong suited for accessibility, but is a step above computer chess matches in the sense it's a dynamic action game with hit detection and an open invitation to engagement. It doesn't have an AI sadly, so the enjoyment you'll get from it(which still holds, BTW), is dependent from your friend playing. There's even a MAME variant out, so try it out for novelty reasons.
