I just played it on both my Nexus 7 (Android 4.1.1) and Toshiba Thrive 7" (Android 3.2.1, they have a 10" version, which is why I specify the size). My comments are meant to be helpful, not a criticism.
It played okay, but I'm not a big fan of the virtual joystick. I can see where it might be a problem on a smaller device or for someone with larger fingers.
It seemed to keep you on the track automagically. I didn't actually seem to need to steer most of the time, except to avoid other drivers. I cranked the speed up pretty high. I'm a rev-head when given the chance, just ask the dude in South Carolina when he told me to 'speed it up a little' at a Myrtle Beach mini-formula one track. The first circuit on the track was to get a feel for the car (don't ever get the yellow one, it will not speed up at all) and the track. My next circuit set the top speed for the day (but I never collected my free pizza). I sorta know what a brake is for when I'm racing, but only use it when absolutely necessary.
It turns out that hitting cows or trees while trying to maneuver around the other players is not a good idea.
The game startup is pretty good. It took a few moments before the black screen changed. I would suggest some sort of promo about the game and/or bukket games instead of a blank screen. It at least lets the user know that something is happening.
The download took a bit (14mb).
The game did recognize when it went to the background and came back in the paused mode. This is a good thing.
Although, the sound continued to play when I hit the home button. This may or may not been an issue with the particular device. It was paused when I returned to it.
Overall, it looks pretty cool (I only tried the Light version, since I was downloading to two different devices).
