Quoted from epthegeek:
That's the plan. Though, at least so far, the dimensions alter the game, but don't have a lot of interactive rules of their own.
There is a water world dimension, with an animated blue light show and it's own music -- but as mentioned, thus far, the dimensions aren't interactive (ie: shoot shots to stay alive)
Right now, the dimensions fall into three basic groups: Points increased somehow (Ramps 2x, Spinner 3x, etc), Game function affected (Pop bumper disabled, flipper function altered) and Feature/Fun dimensions that just do fun/silly things - like Water world.
All subject to change, of course.
A reverse dimension, where the right flipper bottom activates the left one and the left does the right one. All targets will deduct points instead of gaining but the right combination of ramps will grant you double points. The lights are off on the playfield...but starts turning on once you hit the same target that will take the points off.
