Really liked the low poly aesthetic -- the bike in particular looks really good. Just super clean looking overall. I also liked the title screen that shows the name on the bottom of the car, that was a nice touch.
At first I thought that the bike was just way too fast, but as I got used to it I realized that you pretty much have to make it that fast for there to be any difficulty. If it was just a normal bike speed, there wouldn't really be any chance of the player running into cars and such.
There are definitely places where you can get stuck for long enough that you run out of time (Though I never found a spot that I actually wasn't able to get out of).
