wow, this was so good! genuinely dont have any complaints I think your use of this limited form and your ideas around it were so strong, super impressive for the amount of time you have been writing as well. My one piece of feedback is experiment more with how much you can push this, I dont have much experience specifically on fami studio but i know there is an extent that you can really push the sound of notes with bends, vibrato and the like in things like famitracker so see if those options for you exist and how you might consider using them, because it can take this style of music to the next level!
