this is such a kind comment, thank you so much! I'm really glad to hear that you enjoyed it :)
I think for the setting and how it relates to the story, a big theme that I set out wanting to write about was displacement, assimilation, and climate refugees - a world where collapse happens slowly, and society evolves selective resilient traits (like collectivism) to preserve itself. but i think that a lot of the feelings contained are very universal, as you've said. I also wanted to draw on concepts of death and reincarnation/ finding life again after crisis. If you're at all a cautious, or a paranoid person, or if you at all want to preserve the bits of yourself that make you You... it can be so hard.
The game is actually to be updated with an extra scene and a branched ending that "completes" the arc of the story (as well as more Sol moments), so please look out for that! (I hope that we can stick the landing) :D
