Really cool idea, love the comic at the start.
Didn't finish it because I got too frustrated at the 2nd checkpoint.
The lack of resetting the player along with the car wastes a lot of player time and just makes the game feel bad when the camera can't handle the reset. It's kind of annoying that the barrels(?) reset the player, and there's a lack of feedback indicating that it's happening.
Any sort of audio would go a long way to improving the feel of this game, some music and car noises, a crash sound for the car collisions etc.
I would play an improved version of this concept.
