I fully understand it's a joke. Is it a good joke, though?
It takes *ages* to see the final result and until then, all you can really watch is the animation of two ducks and a black text partly on black background. And if you really wait to see the result, it just says "YES", nothing special. Just because something is a joke or a parody, doesn't mean it's automatically excused from all criticism.
See Pico's School 2 or Riddle School 4 as examples of short, obvious joke games which are well-made nevertheless.
