I really don't get the people who comment on a game before playing it just to say "first"...
Other than that, it's a good game, and an original idea. Nice work. 4/5.
Ha, this was my first animation too, but I didn't like the tree or train, so I spiced it up a bit with some more graphics. It was a good tutorial, though.
Nice game if you don't cheat. Also, you don't even have t right-click to cheat; just go to the top where the score is and move your cursor to the finish.
