So while neat usage of 8-bit stuff and I liked the constant change of pace that kind of made me think I'm watching like a crazy Nintendo cutscene from Ninja Gaiden, something about this song is unpleasant. There's a way to write darker, or atonal songs, but this is just not it to me. It's very lacking in harmonic structure which just makes it sound unpleasant, and since it's only 8-bit sounds its more like listening to an angry robot.
I think if you tried to using like a minor or darker key, and still had some kind of chord structure it would come across with more emotion. This just comes across kind of hard to listen to cause its so cluttered and imprecise.
Keep trying buddy!
