Um... I'm not exactly sure what I just watched.
I didn't really understand the story at all. The Toads and Koopas are fighting, there's a bunch of random cameos from several Nintendo characters, and for some reason we're supposed to care about the dog? And why exactly is it titled "Super Duck Hunt?"
Obviously you're very good at sprite animation, there's no question about that. But I really didn't understand the need for all the random characters. Stuff happens and then one minute later it's gone and it doesn't matter that it happened. For example, what was the point of the Triforce, Kirby, and all the Pikmin? What consequence was there for the dog getting shot by the syringe? Why was the dog important at all? The focus seems to entirely shift from the war to the random antics of the dog with no real conclusion. Maybe I'm missing something but I really didn't see a point to this.
