I love the game's art. I think the concept is good, but the execution needs some polish, especially the difficulty.
Placing the blue sheets in safe places to step is good. That way, it's easy to know where to jump or when to brake. The worst part of the game, for me, is the placement of obstacles. It's one obstacle after another, and the precision with which you have to dodge them is very high. My suggestion is to put fewer obstacles (especially in the early levels of the game), give the player more lives, and make it so that obstacles like lasers don't eliminate you just by touching them once.
