The ball can move diagonally! I guess that's better than just the four points of the compass...I'm not sure if I'd have enjoyed this even when my computer was just the ZX81...I still had 2600 pinball after all! Considering A8 pinball games pretty much suck, Codemaster's pinball (whatever that is called) being about the best, which isn't saying much, I don't think this ZX81 pinball would be much fun either. For me, pinball was a failure until at least the 16-bit systems, I never liked any until Pinball Fantasies (Amiga/STe/Jaguar) and Ruiner (Jaguar) came out on the 32/64-bit systems. Even today, Ruiner on the Jag is pretty much the only one I'll play.
But good for the ol' ZX81!
