This is amazing. Everything is done so well and feels very intentional (especially the usage of the piano), and there are 5 tracks! Each one connects with the next, telling an intricate tale, with the use of motifs tying them even closer together despite their vastly different moods. It's just... perfect.
Genuinely makes me wish there was an actual game to go along with this, cause I can so clearly picture it (the description is quite well-written). Overall, easy 5 stars.
