Hey, I vouched for gameplay back on page 1!
Seriously though, I thought it was fun. I liked the sounds and it was reasonably quick. The one at the show had just been made working but was having some issues, and ultimately went down after a day. Still, I liked the gameplay enough to keep going back, I played it about 4 or 5 times.
What I recall is marveling at how that "safe" looking layout - just one outlane on the left and none on right! - was a trap. That pop bumper is set to totally screw you right down that left outlane, especially since the spinner lane could only be hit with a well-timed shot off the tip of the lower right flipper: too late and you're into pop death, too soon and you rebound off the post STDM. You can't trap the ball to line shot becuase the upper flipper opens an outlane right behind the lower flipper, so I was constantly having to battle speed and timing on the fly.
Then the drop banks: GLOBAL was again timed off the lower right and upper left, but the "AL" from the upper left risks the pop nest and that between-flipper out. FARE was off that upper left flipper which was fed by the spinner shot or perhaps a luck pop rebound...
...it was a really fun game in the contemporary 80's style, that kept me on my toes and coming back.
