Great use of the chiptune sound to fit the hardest challenge, I thought of similar things but my composition alone isn't strong enough yet to make a track sound good haha!
It's mainly solid but I do feel like certain parts are dissonant and came out of nowhere. Although overly sticking to the rules can hurt your work, I think this one could benefit from following music theory more while keeping the use of wacky chords/notes to a tasteful degree.
