Nice job! I think this is a really interesting idea, you don't see many games where the car can only reverse. The art is nice and simple, and the music was a nice touch, although some crash sound effects could be cool. My only real complaint is that the tutorial plays every single time you play the game, making it a little annoying if you do multiple runs. Besides that i felt I got stuck on obstacles pretty easy and I couldn't fit through some gaps that I expected to. Great job though!
