I like it! Kinda reminds me of Cruis’n World. Almost came in 7th lol. I like the funky music and the cars feel pretty solid. I suggest something to put you back on the track if you fall off. I gotta a little stuck under a tunnel. Also I suggest you have the camera follow you rather than it being apart of the car. This way if the car flips, the camera stays relatively smooth.
Great start! I bet you can add some really cool features to this to make it fun. Like when you double tap the gas like in Cruis’n World =p
