Very epic, emotional, and overall with interesting vibes and unexpected sounds. I think I would play this game, or at least I would be very curious to try it, since it has a lot of character :)
It is a bit eclectic, and even if that's also a good thing, sometimes it feels like the OST lacks a bit of coherence, but I am sure more tracks would have helped to bring your whole idea to life.
This feels just like a glimpse into something much bigger, but I say that as a compliment. Good job!
