Good 8 bit
I know you were aiming for an 8 bit boss battle... and i think you nailed it, evil and i can safley say a "boss battle" like music. But i am a fan of new and more modern times, and as a game maker am looking for new aged music for my game.
Would've been nice to come here and find this to be a modern song not 8 bit. I think this is why your getting rated so low... no one these days, except "old school" gamers or fan's of the nes system would like this and i've seen a fair few 8 bit boss battles on newgrounds so it's nothing new to people anymore. But keep it up this is a nice 8 bit boss battle piece.
