Oh this is unique sounding, and with bespoke artwork pieces for each track? That's really cool!
This is absolutely drenched in atmosphere and made for an interesting journey. One of the more truly ambient and experimental entries I've heard from the jam. I ended up putting both Zone 1 and 2 on repeat as I adored the vibes captured in both; particularly in The Reefs. Choice of soundscape feels so befitting of the title and had me feeling as though I were floating underwater with all these wonderfully blurry and ambient textures developing and evolving around me.
Zone 3, The Depths, evoked a similar feeling but this one feels almost a little more standard or perhaps typical in its arrangement - not a bad thing by any means, I think it makes it a little more accessible. This works really well as underscore and I could see this in a variety of games. The pulsing synth and washed out melodies drowning in reverb and smearing reminded me of the kind of sounds you might hear in a more modern take of the MGS1 soundtrack.
Zone 4, The Docks, is similar to 3 but leans much more into the passive ambience side of things for me. This has some oppressive air to it and really interesting textures embedded within. I genuinely think this could function as underscore in a lot of modern games - it is absolutely laden with moodiness and an air of unease.
I love the prevalence of a guitar-like melody in Epilogue - it does a great job grounding things and moving them toward a definitive end. The background ambience that pulses and washes in the background keeps it nice and congruent with the other tracks but that choice melody and progression adds this whole other layer.
Great job with this, it was a delight to experience and it has a lot of really interesting ideas and sounds present. Definitely one of the more unique ambient submissions I've personally heard - I'd love to hear more!
