First of all, glad you got something working, sorry to see you're having unity issues on your first game, keep at it though! Anyway onto the game, it's quite challenging and the limited art style makes it looks quite cute. A slightly higher camera angle may have been appreciated however, but it did add to the challenge of the game so I guess I'm not sure? :D... The sensitivity of the car is quite slow, not sure if that's on purpose though. If I was going to nit pick I would say you could grab some sounds from opengameart and I also always appreciate a pause menu and quit button, even just escape brings you back to the menu and the menu has escape? Finally with nit picking you could have a restart button, r just reloads the same scene or something... Anyway for a first game this was actually quite good... better than mine anyway! :D
