This game looks pretty awesome. I've been meaning to give it a try ever since it was released but I just haven't got around to it. The constant stream of downloadable content and unique puzzling mechanic certainly make it appealing.

You really should. There's a lot of stuff to do with it - online play, hundreds of puzzles (not even including the hundreds in DLC), puzzle creation and sharing, and some minigame or time based modes.

you need to come back to Gamespot.
