Good game! It was easy to get into since the mechanics and controls very simple. I think it has a very clear design and a coherent art style. The biggest problem was lack of information. When the cars follows a specific direction you want to have some way to know how to line up the roads. Otherwise it becomes a guessing game, which becomes quite frustrating when you can't restart the level :P There were also some issues with roads lining up weirdly. Sometimes the cars seamed to be able to pass through things that they shouldn't (visually at least) and sometimes there were straight roads that had to be in the correct direction. Overall though, great work!
