Decent little racer. I especially love the low poly aesthetic and the colors! I think the racing mechanics could be refined a bit as it was pretty easy to stay on the road and make turns. It seems too easy almost like I was being guided by the game.
EDIT: Playing it again, it looks like you can't even drive off the road. Also, I would suggest including the timer during the race, so players can better keep track of their time if they want to climb the leaderboard at the end.
Anyway, though, nice job!
