Just wow, I had chills and I laughed as it was just impressive and beautiful xD.
The wind sounds adds a dreamy, heavenly atmosphere ; the reverb and sustain on the piano is so soft, and it's so sad without being overly dramatic. The glissando at 0:57 followed by the unconclusive chord at 1:00 is gorgeous. I don't know which instrument it is at 1:04 in the background, maybe a vibraphone or something like that, but the distant sound adds another layer and it sounds great !
The change at 1:30 and the drums at 1:36 are a great build-up and from 1:40 to 1:42 that little pause with only drums playing really enhances the climax as it arrives with more power with a big drop.
And at 1:42 is when I started to have chills and I laughed at how beautiful it was, it's breathtaking ! The rythm on the drums is radiant, especially with bits like at 1:55 that makes me shake my head. The melody is also magnificient.
And the ending is one of the best ones I've heard of. I like how the climax part ends in the highest note, then pause, then it ends softly, but still with the power and the memories of what happens before which adds more strength. And that hang-up at 2:12 is the ice on the cake.
One of the best in this music jam so far, keep doing what you do, that's an impressive work that could be in a real game with you as a composer !
Edit : the story is sad and beautiful, really bold and it adds all the emotions in the music ; would love to have game like this !
