The concept could work, but at the moment it does not.
The car is pretty uncontrollable and the camera shakes pretty uncontrollably.
The game feels kinda unoptimized, it got laggier and laggier every time i added an obstacle, and they were just in the way but did not really make the game any difficult and i always managed to reach the end, I got to a point where i had obtained all the hazards, some of them multiple times and the camera was shaking a lot. At a point it rotated really fast for some seconds. I then quitted.
I'm sorry to say that I did not like much the graphics either, they seemed messy and I think the gravel's(I think the out of the road part was that (?)) texture could make people dizzy or naseous at that speed.
I'm sure if this gets worked on it could work though, so keep going and never give up!
