Quite hard from the second level, the time to decide things are quite unforgiving but through trial and error you can figure it out. I will say though it is frustrating when you miss a click by just a little bit and the whole run ruined but since the stages are usually short it doesn't take long to get back to the point you lost at. Simple graphics but the animation you have when the trains are probably the best part of the game quickly stood out to me when it happened, nice job there.
