Funny game! I love the setting :)
The controls are simple, the music is quite fitting and catchy, the mechanics took me while to get. When I read I can crash into the side of the trains I assumed I really need to crash it and was a bit confused that pressing left or right did nothing to crash. Then I held down the key and understood how it's supposed to work and then it was "Choo, choo, here I come"!
Nice visuals and cool explosions!
My only complaint: I'm too old for games that require quick reflexes like your game :D
Good fun. Well done!
