Cute art style. I loved the roundabout level, it was a very creative use of the switch lanes mechanic.
I would have loved it to be a little bit faster since I had to wait a long time while I already solved the puzzle :D Also, there is a bug in the 3rd level, if you do not click the start button the yellow car gets stuck and you have to restart the game :/ But other than that it was a pleasant experience :D
