Oh, this definitely is some of the better 8-bit stuff I've heard. Very pleasantly suprised! :)
The intro gave away that it'd be at least decent. I really like the ominous / mix of tranquility+sadness in the intro, it provides an excellent atmosphere. I have to say I was a little bit surprised at how 'happy' and 'upvibe' you actually made the drop, because of that. You use a lot of those high pitched perc hits, such as the one that almost sounds like mario forcing himself down a green pipe. I dunno.. it feels like it could've held on to the vibe it had earlier if you downpitched them a bit, or lowpassed them even.
Then afterwards, you bring the pads back in and it sounds like that again for a while, but only shortly. I was a little disappointed at how cross-over you went with the components of this track, to tell you the truth, but considering it all was mixed in rather nicely and the melodics themselves are produced properly, I suppose that doesn't really matter. It's just that I personally would've liked to hear you take it in another direction.
But really, this is your own music ofc and it's definitely produced alright, so good job! ;)
