I can finally say I've played it at this weekends Rocky Mountain Pinball Showdown. I have to admit it plays very well. Its very intuitive to interact with and IMO that is the mastery of the design and it ties in very well with the them and story. Its quite an impressive and smooth playing game and stayed busy with a decent line all day Saturday when I was there.
I still stand by my original comments about the art and theme, it unfortunate that a better story and art package doesn't compliment the game design. I'll add that I didn't hear any comments myself along those lines, and everyone seemed to respond positively. No doubt it will do well, IMO glad to have played it.
