Pretty fun!
Bit of criticism, the hit box on the car seemed to be bigger than it actually was, I died a few times when taking a turn when the car's sprite didn't actually touch the wall. Also if you're too close to wall and try to turn when the car's sprite shifts it'll be in the wall and you die. I feel like the game would feel better to play if the player was a bit faster too, I had trouble some times getting ahead of the car to shoot away the boxes. I also found it pretty funny when I beat the first level only to watch my car still explode as it kept driving past the finish into a wall. Other than that it was pretty fun to play!
Oh also seemingly randomly the game would play a really loud crashing sort of noise, bug maybe?
