Drive A Tank!, is the first of the 8 levels which teach you the basics.I would recommend completing them before buliding your own incredibot in sandbox mode or trying the challenges. It impossible to call one level harder than any other, as they are all incredibly easy, so I won't. In this level, you do not have to edit the tank at all, just understand how to use it.Your goal is to hit the play button, drive to the left, over objects of varying shape and size. You must then drive down a steep slope. Falling over does not matter, as you can flip yourself over with your arm. Then you have to lift the blue square into the pit a very short distance away. You then recieve your first check, and the knowledge of a tank design.
