The wheel controls the majority of the movement. The harder the turn, the quicker the movement. Clicking the switch nearest to the wheel on the right will switch from legs to arms. The one on the left will turn the controls from horizontal to vertical, allowing for ducking. The pedal is your ability to jump.
But, we should be far enough from the town for you to get a feel for that on your own.
