Wow there is a lot going on here. Between chromatic scales, steep pitch bends, and some areas of notes splintering off and remerging on a shared chord, there is tons of movement in these pieces and all of them are distinct.
The piece Kesasota is the most energetic with some crazy drums in the back.
I enjoyed this more than I assumed I would going in with the knowledge that it was limited to chiptune NES soundcard.
This was very impressive and kept me guessing throughout. Great work!
