The game is very nice and surprisingly simple. I got a bit scared by the tutorial, which was obviously intentional and funny, but then I felt like I had to travel 10 kilometers before reaching the first station... I even started to think there were no stations.
The background is beautiful, and the entire game is very polished, but maybe consider fading out the braking noise the longer it plays.
I had a great time, but after a while, the gameplay became a bit repetitive. You might want to introduce new hazards or setbacks to gradually increase the difficulty. Great job!
