As scrunglium already mentioned, the music doesn't loop, which is a shame because I actually really liked the music, and the game closing when you die is a bit abrupt, but I really enjoyed this one. It is a very original idea, and there was a lot of freedom in what to do. It was really cool trying to decide at times whether or not to stay on a train because it would drive away if I left it, and I liked that and a lot of other things like it. The art is also really nice. Great Job!
P.S. My biggest recommendation would be to add a thumbnail as the lack of it caused me to go a while without trying this one, and especially when your art is so good, having a thumbnail would probably help bring people in!
