If you are looking for a top-notch puzzle game that cleverly uses three-dimensional space, Puzzle Dimension is definately the game for you. The puzzles are mindboggling and each one is both clever and unique. You're goal is simple: traverse the puzzle to collect all the sunflowers and get to the goal without falling infinitely, being spiked, roasted alive, or otherwise incapacitated.
The game creatively adds new mechanics as the levels get more and more difficult, and each add a whole new level (or should I say, a new set of levels, for each mechanic has its own group of levels focused on intorducing and using it) to the already deep puzzler that it is. The levels complement the mechanics well, and they are all challenging and fun to solve. I've finished about two thirds, and it never stops dropping new ideas and challenges on you.
The graphics are simple, and they do the job well. There are four options to choose from (all showcased in the trailer), so you can change how the game looks to your liking. In each texture, you can still easily tell the difference between the different types of tiles, even if it does take a little getting used to if you just switched. Music is also quite catchy with a nice retro-ish style to it.
The biggest issue with this game is the controls. This is a console port, and boy do you know it after a minute of rolling the ball around. Arrow keys for movement, okay. WASD for six-directional camera, I'll live. The jumping however, is very clunky. Once you hit space to jump, you cannot change the direction you are going. This means you have to time your jumps between the time you press an arrow key to the time you roll off the edge of the block. This certainly isn't a dealbreaker, and I stand by my reccomendation wholeheartedly, but this is easily my biggest gripe with the game. That and invisible platforms.
All in all, Puzzle Dimension is certainly worth the low price of admission, and if you can get it at one of the many times it is on sale, it's a steal. It is easily one of the best puzzle games I have played and one that uses 3-D space in ways most puzzle games don't bother to explore. At the very least try the demo. It will show you if you can stand the controls and how much this game has to offer.
