I really liked your soundtrack,...like everyone else :D
An like that I really like the overall look and feel of your game, pretty chill.
But why writing a comment when there is no constructive critic, so:
Your collision detection gave me cancer. For gods sake you can't die in that game. What I mean in special is that the bike has the colliders down on the wheels, what is correct. But some of the obstactles have their colliders on top. So driving on top lane leads to hits when it really shouldn't do.
