What does Shellwood make you feel?

I was listening to the soundtrack of Silksong, while searching for music to use in my DnD campaign, and I became quite unsure of what emotions and feelings Shellwood is supposed to convey?

What emotions or story is Shellwood trying to tell? (not just in music)

To me, the music is quite mournful, and the area is seems somewhat dead, but what is the point?
