Wayy the fuck over my expectations bro! Absolutely brilliant! Pieced together nicely, and does justice to the original! Temco would be proud of you and the way you arranged one of theor greatest hits of all time! Its good to have you back as well! The ending was pieced together nicely with your usual flares you throw in which made this piece scream Burn7 in every shape and form!
Listening to this on my bluetooth headset, everything is balanced to the T, and in saying that, I welcome you back to the light of newgrounds!
As far as licensing and being in violation of the Community terms and rules, naw. You did everything right, and this tribute is just that, a tribute to one of the greatest NES games of all time! While on par with Megaman, LoZ, Mario, Metroid, and a few select other titles...you do Homage to those artists, and they would be absolutely PROUD of you and your work!
