wow
I definitely recognized it, it's one of my favorites! The hammer brothers battle theme from Super Mario 3, right? Even though i noticed "NES" and "good song" in your introduction, it never occurred to me... haha. I'm not sure i liked the mix much, but the artist definitely put effort and love into it. Some parts of the animation were awesomely synchronized with the sound in the beginning, but i didn't notice as much later.
