I haven't played it but they just discussed on the The Pinball Podcast and they say that it's a nightmare to keep up and going since its got 3 play fields and lots of stuff going on. They also mentioned an electrical shorting issue that was common with Gottliebs of that era.
That being said, they also said it was really fun, especially for a more experienced player. I think the art package and theme look awesome, unfortunately I have not had the joy of playing one... yet.
