psst!
One of the Docomodake trailers I worked on is online, finally!

and in case you've never heard of Doco (which is a distinct possibility), here's a blip from IGN's review of them game:

From the slim amount we've played so far, this game is in fact seven kinds of awesome; at least the first few levels are. This is one that came out of nowhere for us, is now sitting in our DS (and was played for a bit over Thanksgiving Break), and is surprisingly fun. Oddly enough, this tiny fungi of a creature is actually a mascot for Docomo, a Japanese cell phone carrier, and has become a pretty impressive little celebrity, spawning instructional "how to visit Japan" videos, waves of merchandise, and now - for seemingly no reason, or even acknowledgement of its ties to the cell phone business - its own game. What the hell?
But alas, if you were to ask us whether we enjoy the company of a gigantic mushroom, we would say yes. Yes indeed we do.

I was lucky enough to play (and beat!) an advance copy of the game over winter break and I can safely say it's a phenomenal way to waste some time. It's entertaining, simple without being boring and tricky without being annoyingly so. A good thing to play on your lunch break or while waiting in line...or while stuck at an airport. Go buy it!
