Pull back on the mouse in the opposite direction of where you want to go. Then an arrow grows in the direction you want to go, the larger the arrow the fast the player goes. like pinball. When he's in motion then you can steer just by moving the mouse. The faster he goes the harder to steer he is.
Click once to stop and if a new movement is entered the player slows down to a stop then takes off again so they don't just keep shooting him places.
