Good game, but it has some minor errors. First one is that when you start level 2, you don't have your chosen scooter anymore. Second is: if you mute the sound, it suddenly pops back up again if you complete a level.
Quite repetitive after a while. And also a little boring...
Maybe mention in the beginning how many trials there are. That motivates the player for playing it to the end
After the first actual level?
