I'm very surprised and pleased by how much the melody varies through this track! Usually most songs I hear just repeat sections of music with variation to it (which is fine of course) but this just keeps evolving as it goes on for almost it's whole duration! The modulation on some of the instruments sounds very authentic to the old 8-bit style, and the melody is very nostalgic. This would fit perfectly in an action scene in some NES game or something of the sort. You also have both a perfect start and finish to the song that makes it feel complete. Amazing work, keep it up!!
