That's pretty damn sweet
this a kickass rendition dude! I enjoyed the 8bit beat, that super-cheery fluteish sounding melody, and those "fireball" sounds. Do you have an arpeggio in there that is played in Mario when you get a 1up as well? Real glad you included some originality, interlude is the best part of the track. Also sounds like you got the original themes nailed right on too, great job.
I dont really have any criticism to offer. Sounds great in 8 bit type of way!
