Incredible work, I opened this up and left it playing while checking something and genuinely forgot this was an entry to the jam and not some soundtrack I'd left playing.
Off the bat, great orchestration and tasteful arrangements. Each element sits so well in the mix and there's a lot of instances of space left between notes to really allow composition to breathe - something I think is missing from a lot of entries, my own included. A lot to be said when it comes to less is more.
I really like how you've managed to instil such eerie and anxious aspects into some of these; Echoes of Silence is a prime example of this with the shift in string articulations and the ominous droning. This does carry over into Gates of Thalassia which gives me a little bit more of an epic unknown kind of vibe at the beginning. Choice of orchestration throughout this one in particular is gorgeous; soft but meaningful. Progressive but still caught in the moment.
All in all this is a fantastic mix of tracks, all of which could easily fit into a video game without question. Really good job, you've got the chops for underscore for sure. Could see this going deep in the rankings!
