Quoted from SKORR_Arcades:How about after a few shots on the upper playfield, you are forced to go to the lower playfield - so that doesn't get exploited. Or maybe if you are on the upper playfield too long, it gets harder to balance the sandwich - since you always have the opportunity to cash out by hitting the action button.
And have a sandwich making high score with the picture of the final sandwich - since Bug mentioned to show him our highest sandwich scores.
Given that the upper playfield has Capt Cutler skulking around should mean there is a lot of sea water sloshing around...the longer you are up there the sandwich base could get soggy, the soggy-er the sandwich the more flimsy it gets, draining to the lower playfield drains away the water and dries the sandwich out a bit. Water slowly builds and slowly drains depending on how the timers are set?
As for an OPTIONAL video mode I'd like to see something like the gang driving the mystery machine on a crazy spooky track (creepy forest and or foggy mountain road) dodging obstacles, shite weather and all the while the windshield gets pelted with bats and more bats obscuring the view as you go...flipper steer the van and action button flips the wipers to clear the windshield? Start character your playing is the driver of the Van and each has there own driving style/perk/detriment...
