I wouldn't normally say this about a game, but this is just too easy. The challenge doesn't ramp up at all until the level before the boss, and by then you've got enough money to upgrade almost completely. Died once in the whole game, and I am not really particularly good at games. Very well made though, imaginative enemies!
I thought this was the hardest racing game I'd ever played, until I found that if you turn 'engine' and 'handing' up to 100, disregarding boost, it becomes much, much easier. It's ok as a game, but I agree with Lloyd Majere.
