Rotate leg up when spacebar is pressed, next have it pick up items.
Getting rid of scale everywhere except top level.  Am picking up item but it disappears.
Can pick up items and they are visible, now add a dropItem method to Level.
Can now drop items and pick them up again, next make items interact with obstacles.
Can now open the door with the key.  The key and the door simply disappear, and the cat can walk through.  Later add sound effects (more important than animation).
