Such a cool track! It does in fact remind me of some N64 tracks (like Koopa Troopa Beach, Mario Kart 64), you really achieved everything you went for, great job!
And of course I loved bubble synth as well :) Perhaps, if I were you I'd probably shifted the whole bubble track a few ms earlier to compensate for its slower attack. Especially at the solo, it seems to water-down the groove (pun absolutely intended).
And "playing steel drums in middle school"?! Now I'm absolutely jealous! Such a wonderful instrument, yet so unobtainable in most of Europe (at least at the time, nowadays you can probably get one for $100 from thomann or something).
