Amazing.
First of all, I'd like to say this undoubtedly the best animation I've ever seen so far, and to top it off, it's about Miyamoto, one of the best video game designers, like, ever.
The animation was really smooth and fluid, and the music had a catchy beat to go along with it. The concept's great, It's really interesting to see him explore all all of those games he created and travel with along the characters, beating the stages. It's sort of like seeing what he was making all of these iconic characters who pretty much changed the course of video game history.
Great job, don't stop making flash.
