It's not really polished. There's no music. And almost all of the in game graphics are borrowed from other games. So I guess it's polished in the sense that those other games did the polishing. It really does come off as someone who started out trying to clone Mario, or someone who was just trying to make their first game without expecting anyone to actually download it. The lack of a paid ad-free version shows that it wasn't really expected to be downloaded millions of times.
