Really fucking cool! I played with my wood train tracks for hours every day when I was younger, this took me right back to those good old days. The solutions were interesting and creative, and like Sander said very cool and out of the box. If this was like one of those offline android games with hundreds of levels I would probably spend multiple plane flights and car rides replaying this game. It doesn't fit the theme very well, except if it directs to the player (me) being stupid and working.
