I like the simple mechanics of the race, and a high score system.
I couldn't quite do the thread and air stuff, because to be at the first place, you have to drive ahead of the other 2 cars and this makes you just hold w and by that, you cannot see the ramps and the cones that give you style points.
I think you put this system so that the player has to slow down to do those things, but the environment of the game made me to accelerate in the early and mid game, and just drive safely after the hounds.
Anyway, good work on the 'retro' stuff!
