Really amazing work!
The opening is quite nice. I'm imagining some sort of cutscene unfolding. Love the flute melody. While I like the idea of the piano note acting almost as a metronome, near the end it sounds a tiny bit static though. I wonder if it could've benefitted from a little automation of its reverb or something to make it sound a tiny bit less static. It's a very minor nitpick, but just something I noticed.
Okinoa Town sounds nice. It indeed sounds Town-ey. It also sounds quite happy and peaceful. I feel sad that Okinoa town is gonna be destroyed.
Exposition is so lovely. It's incredible and it is easily my favorite from this soundtrack. It sounds both melancholic, but not just depressing if that makes sense. It definitely has a sadness and a very heavy weight, but it still feels like we're moving towards a goal. It feels like our character is not going to just give up. Like hoping for a better place and then moving towards it. Onwards towards something better! I really really like this one. It's absolutely gorgeous. It gives me Yann Tiersen vibes.
Final fight sounds pretty satisfying. Especially after Exposition, I'm really rooting for the character to overcome this weight that is on their shoulders.
Also, props for the very nice cover art.
