really dig that melody it's super hot some of the notes seem to lose volume oddly throughout the song, not sure why. The beat is very trancey but that's absolutely fine because because it fits with the song. but when the bass synth comes out, it's a bit too loud because it starts pushing the other frequencies out at the beginning, but when it comes back in it seems to be a bit better . It's really important during mastering to make sure that you balance all the sounds, otherwise you'll start get a squashed sound that makes the song sound unbalanced.
the only other thing i can notice is at certain points in the melody the notes seem a miniscule amount offbeat, but maybe that's just me being picky.
Either way as far as the song itself goes, it's great aside from some mixing issues it is really fun and enjoyable to listen to. I really like the sound you got for your 8bits and would be interested in that plugin if you could tell me where to get it. Keep it up man. I really enjoy it.
