I have no real issues with the mastering. This sounds like a pretty generic 8-bit track. I guess my overall curiosity is with the composition. The intro was pretty clashing for me. There was a moment where the first melody came in after the intro and then they kind of worked together in a really weird and unexpected way. I definitely see potential. I would really focus on maintaining this strange and weird melodic style. I wasn't a big fan of how you incorporated it in this song, but I definitely see how you could make this sound really cool and strange at the same time. Overall, good job, keep it up, and I hope to see more from you.
