Could you give us more information?
How would he move left and right? Is this like a platformer/Point and Click adventure hybrid?
I think a good idea would be to get input from mouse, and once clicked on an object (like a move left/right sprite) it would take you to another layout.
How I imagined it is the player would move towards the direction of the click but in a linear manner, just left and right. There probably would be a grid with a list of actions to choose from (like in games such as Monkey Island) at the bottom of the screen or something.
So in your idea would there be no animated player?
