Quite Impressive!
That was actually a suprisingly good game! Even though I never managed to beat it, it was still fun to play a few times over again. I liked the interactivity and controls, and also how the different obstacles moved at different speeds to each other.
The only improvement that sticks out is the graphics for something like this. If the ground was drawn with a lot more detail into perspective and perhaps a background it would attract a larger audience. The same goes for the cars, something as simple as letting you choose between 3 different colored cars with different styles could greatly influence someone's opinion on the game!
