Not embarrassed to say this is a great game. Yes, its a simple rule set, but not always so easy to achieve. The rotating island that provides 5 different shots from one ramp is awesome. I have two relatively minor issues with mine:
When I bought mine, the coil the shoots the ball out of the Shells lane was toast. Rather than replace the coil, the previous owner screwed a post into the shell lane instead. I've fixed the coil but now have a hole in my playfield. Not sure how to fix it or even if I should as its barely noticeable and doesn't affect gameplay.
Occasionally, when the island stops rotating the game will reset. Usually this happens when you first turn the machine on and as it warms up the problem (mostly) never comes back. For the most part it works, but I'd like to get this fixed. I've heard its a common issue.
