Definitely a nice listen, I don't listen to ambient, calm stuff much so this was a nice change of pace, and the few more energitic tracks stood out quiet well
The one thing that really stood about this is how all the tracks flowed into each other, downloading this and putting it on foobar2000 felt like listening to one big song. The way the lighthearted feeling of the soundtrack faded when going from Sine to Gaia, and entering Thunder and hearing "normal" hi-hats after all the ambient tracks felt really cathartic.
My favourite track was probably Nkumo Atoll, it tells the story of arriving on the foreign island, looking for and finding your brother, running away, then embracing the sun despite all your trials wonderfully. I actually wanted to ask what your inspiration was for naming the song that way, I couldn't find much about the word "Nkumo" online (except a website that translated it to "forehead", I'm not sure if a forehead shaped island was part of your vision lol)
All in all, well done!
