i made it to the top of the huge ramp, not sure but i think that was the end. has a trackmania vibe to it.
the car looks great, and it handles well at low speeds, but at high speeds it gets too bouncy. That being said this looks like an old muscle car so that might actually be realistic. I also think it would be less of a problem (the bouncing) if you smoothed out the track. something i think that would really help is level select and a timer that saves your fastest time for the track. I did not have much issue keeping myself entertained even with that tough curve in the last level (a little more grip would have been nice right about then.) Sound effects, some track textures, they are not really necessary to make the gameplay fun but would help immersion.
slight bug when resetting it should remove velocity, sometimes it would throw me off the track immediately.
