Puzzle Dimension is a mind-bender. Don't get comfortable with the idea of rolling that little marble around and hopping over a few obstacles. The game soon turns everything upside-down, literally. The ball follows the board as it curves around and back over itself. Although the ball doesn't strictly adhere to gravity, it does always fall to wherever "down" is. If this seems hard to follow, it is. It takes a little getting used to.
You'll have to learn how each new tile you encounter works before you can proceed through Puzzle Dimension. The special tiles you first encounter are the Ice and Breakaway tiles. The Ice tiles will not allow you stop on them, and will push you out to the next tile you were heading toward. The Breakaway tiles will only allow you to roll over them once before they break away. Later you'll encounter tiles that catapult you, that disappear, and even spiked tiles that will somehow kill your poor ball. The use of all these special tiles means that there's a very limited number of solutions, if there is more than one at all. Of course, that's a puzzle game at its best.
There's not much in the way of special items or bonuses in this game. The bonuses you earn are based on how fast you "convert" the map from its original pixelized state to its "prettier" end result. So, if you're a speed demon, you can grab extra points. But there are no bombs, jewels, or other gimmick items. You deal with the obstacles you're given, and you figure out where you jump; that's pretty much it.
As a side note, I'm not the kind of person that gets motion sickness from playing first-person shooters, or anything really, but this game made me understand that queasy feeling. If my eyes were connected to my stomach in just the wrong way, yep, I could see this game causing some problems.
