Great puzzle game. All levels are possible - none are too tricky. Luck plays it's part (but not too much, I think. I like the balance) - some levels involve playing the right strategy several times until it pays off.
The collision detection is a little off as well. Not by much, but with this kind of game it has to be perfect.
And that oversteer is really annoying in tight spots - the back end should not slide sideways like that.
OK concept, but needs refining. Physics needs work - big oversteer. Keyboard conrols for steering would be much better. A bigger field of view would be nice (ie maybe zoom out a bit more).
2.5/5
