Whoa... You made this?? That is... Very very very impressive! Not because Knuckles is one of my favorite Sonic Characters but the whole rendition. It's so close to the original it's not kidding. I was about to think this was promotional work for a new Sonic game and I was like "Finally!" But yeah, very awesome job, I'm just blown away... What program did you use to make such a rendition if you don't mind me asking?
