Very nice entry! Unfortunately I missed the screen telling the story, so i was a bit confused when I was suddenly climbing the wall. Maybe you could add a fade out transition or a particular button to click so that people don't accidentally click past the important info. Good premise though in that story, once i read it :)
It would have been nice if there was a goal to climb towards. Dragging the limbs with the mouse is a bit slow, but i imagine it working great on mobile!
