I'm not usually one for puzzle games but the positive word of mouth around Pushmo led me to purchase it before going away for the weekend. It turns out 6.99 buys you a lot of game these days and isn't indicative of the quality. For what it's worth, Pushmo may be just a plain better game than most 3DS retail releases.
Not that the story really matters here but Nintendo has cooked up a short little tale to give you an excuse to solve puzzles. Some small cartoon kids have gotten themselves stuck in Pushmo's; block puzzles that can be compacted. It's your job to help rescue all the kids as Malo, a rotund sumo wrestler-esque protagonist. Any avid puzzle game aficionado probably knows that the meat of a puzzle game usually doesn't revolve around the story and with Pushmo, the paper-thin precursor to the gameplay is cute addition but easily forgotten in a few minutes.
Gameplay is very accessible and easy to understand You move Malo with the analog stick and only use two face buttons, jump and grab. You must expand the three dimensional blocks from their 2D shape by dragging them towards the screen and then climb the structure to reach the distraught child. There is a mild amount of platforming involved but the real challenge comes with figuring out in what order you must pull out or push in the variously shaped block pieces to reach the top and save the kid.
In addition to providing over 250 puzzles for you to solve, the game also allows you to create your own Pushmo puzzles and share them with your friends via QR codes. In theory, there's infinite puzzles to play, which for 6.99, is a heck of a bargain.
What else is there to say. If you like Picross, you will like this. If you are looking for a mobile game that's actually meant to be mobile, Pushmo is the game for you. Honestly, the game is just a joy to play and may be he best time I've spent with the console outside of Street Fighter IV. This may not only be the best E-Shop only puzzle game but perhaps the best E-shop game period. Pick it up without reservation.
