I played it for the last 2 weeks at the local pinball place and I really like it, I drew a few comparisons with some of the shots
Left lane before the left ramp - Same shot on WWF Royal Rumble.
Right lane when the ball drops out of the ring - Also like WWF Royal Rumble
Bonus score at the end of each ball - Seems like old school Genie pinball
Centre Loop - Kind of like Fish tales
All in all with more code it could be a killer game.
