pretty cool!
i gotta say, this definitely does sound retro, makes me think of the old genesis games i played at home. anyways, great production, the background bass and claps could be just a bit louder but aside from that i don't see anything wrong here, it'd fit perfectly into a flash, game, or hell even a small movie if push came to shove (though i don't make the first two, just movies, lol)
keep up the good work!
