Roof Rails is a casual game where you play a character who has to jump from one roof to the next while holding extra-long rails to keep you up.
Much like what happens in similar games, your mission in Roof Rails is to advance throughout the settings without falling to your doom. You'll do this by making sure your rail is long enough to hold you up when you need it most. As your character runs along the platforms, you'll come across obstacles that will cut your rail and shorten it. So you need to make sure you run over and collect the little pieces of rail that you see scattered around the roofs. This is how you'll keep your rail long enough and avoid falling to your doom.
The interface in Roof Rails may be simple, but the game will still hold your attention thanks to its 3D graphics. Plus, it has intuitive and user-friendly controls; so you just have to swipe horizontally on the screen to move your character left and right.
In short, Roof Rails is an incredibly entertaining game. Jump from roof to roof and keep your rail as long as you can to make it to the finish line with as many points as possible.
