Plain graphics are simple and cartoon-like in this game. I think the obstacles you move are the main mechanic. The train must go through every level without hitting anything. You can collect coins to get new train skins. That is the main thing you do.
Step to move obstacles is how you start playing, you need to drag the track pieces so the train can pass.
Clicking to move obstacles is how you start playing. You click and drag to make the path clear.
Simple is the best way to describe the strategy. Most players find moving the tracks early is better than waiting.
