Delve Within The Soul absolutely makes you want to hear more and play the game. It has a really nice depth to it that fits the idea of dreaming but also has a lot of drive signaling a journey. The vocals are especially beautiful.
Crossing The Depths of Sorrow captures the image of a sea of sadness really well. Depending on the imagined story it could have been even more sad in my opinion.
Soaring In Ambition makes you want to fly into the sky as well! I love how uplifting it sounds.
FEARMONGER creates a lot of hype which is very fitting for this point of the game. A banger!
All in all this soundtrack reminds me of a mix of gris and undertale/deltarune songs. I love it! The progression is very well done.
