In this tutorial you will learn how to draw straight lines in Line Rider. It is so easy that you will be stunned. This tutorial will work on Windows.
First make a short hand drawn line so that the sled will begin at the right place.
Left click where you want your straight line to begin and while holding the left button press the right button (right click menu will appear, ignore it)
Release the buttons and drag the mouse to where you want the straight line to end and left click.
Congratulations, you just created a straight line in Line Rider.
