We are deeply sorry for this inconvenience. What exactly does happen? Does the car appear? Does it rotate? There is a known bug, that after loading the second car level the car stops, but it will move again if you click one more time. Keep in mind that the timing to move the car is very tight... (I will fix those listed non game breaking bugs after the GameJam because of limited time!)
Thanks again for giving it a second try!
