+1 to Black Hole , I do own one though , so i'm a bit biased
. I like the challenge of having to hit a complete set of targets down , when playing downstairs , failing to get a full set you lose the ball ....
I havent played all multi level games from that era ,so they maybe a few more that are good playing games. others might know.
I really enjoy JJP Wizard of Oz upper playfields, Esp the upper left playfield "Castle Rescue" What a amazing game!
