Nice man! ^_^
This is cool, man. You should've called this "Mario Techno" instead of "Nintechno." :P
But Nintechno's still a good name for it, tho :)
Anyways, about the song...
I loved it! This is so cool. The beats are so cool. And the whole DJ thing... i can't remember what those were called... disc scratching? lol. Those were cool, too.
I'm so going to download this, man! Good job! :D
