This sure came out of nowhere. Goddamn GREAT game. One of only 2 or 3 games I've been willing to pay the full 1200 points for in the console's history.
Best XBLA game since Trials Evo and probably even better than that. Easily in my top 5 of this year so far. Definitely seems like one that'll actually get better as you get unlocks and go back through earlier levels.
