I like it and I respect Koji Kondo and his music a lot, you did a good job, it is really messy though..
Yeah, I'm not really good at recording stuff like this (I'm an electronic producer anyway), but I can play guitar and I gave it a shot, this wasn't intended to dig at Kondo, I respect him as well.
Please contact me if you would like to use this in a project. We can discuss the details.
