This is a wonderful soundtrack. The opening is amazing. I really love those swelling synth pads. They really gave me goosebumps the first time they come in. Somehow they make me nostalgic for a game that never existed. The flute then forms a nice addition which complements it really well too.
Also really love the combination of synth brass with piano in the overworld theme. I think those two are definitely my favorites in this soundtrack.
The guitar sound in River Reflections is also great.
Unrelated to the music itself, but I also think that screen capturing the actual DAW was a nice touch.
