Haven't spent much time with it (snuck in a few minutes at work), but so far it plays like Mini Motor Racing but with simpler/cartoony graphics, better car physics (you can flip over, for example), and longer and more involved tracks. There are also hazards, like in Reckless Racing 1 & 2, as well as destructible environments. Drifting seems to play a big role. The default controls seem good -- not sure if there are other set ups. The game doesn't seem to skimp on the content.
I'll try to spend some more time with it and post later tonight. I'm not a huge racing fan, so some of the nuances may be lost on me. So far, though, this strikes me as pretty solid.
