nage one or more crossings, including some special ones that change the train's track and make things much more difficult.
Another element of Paper Train Reloaded that makes it more difficult is the speed of the trains. By default, trains go quite slowly and it's relatively easy to manage them. That said, if you want to get three stars on each level, you'll have to press the accelerate button to make them go faster. The problem, of course, is that this makes everything much harder.
Paper Train Reloaded is a very entertaining puzzle game with more than 300 different levels. Visually speaking, it's quite charming, with graphics that resemble hand-drawn doodles on grid paper.
