I agree this looks very polished right from the start, nice work. My main feedback would be to have it a little easier at the beginning (the steering was way faster than I was expecting!), it took me 7-8 attempts just to get a time fast enough to open the second track. I know from my experience when developing a game I get too good at it while testing and forgot it could be pretty hard for a new comer. :) Or maybe I'm just old! Overall, well done.
