CC on a track I made then played drums on

i dig your playing man! my main CC would be that during the louder parts you might bring up the gameboy volume, either in post, or using M commands (or both), since the louder drum parts (around 1:20, and again at 2:05 for instance) make it harder to hear the lead. also, for the lead, maybe consider changing the duty cycle, maybe use a few extra P commands or E commands to add some extra variation to the sound, to enhance the flavors. keep up the good work!
