Nice game but there is no end to this game. When the rails is totally cleared from the rocks and wood it will take ages for the train to reach the end of the rails. Ofcourse I wanted to find out if there is a ending to this game so I let the game running while I was watching tv. When the train reached the end of the rails it just kept on going and finally when the end of the map was reached the train still kept on going through the air. See the attached image.
So please make a real ending for your next project.
