I really like this piece of work. It felt as if all routes really happened, and at the same time, none of them, because ultimately the linear nature of the narrative and the mood prevail.  I haven't played a lot of interactive fiction, but it seems to me that you used the format in a way that is really conducive to the telling and themes of the story.  All it really takes is one lingering thought on the wrong thing, right? And it'll affect your whole attitude. 

I really liked this! The writing was great, it was really interesting seeing what had become of the world and seeing how Sierra and the protagonist survived. It had a really melancholy feeling to it... I loved the ending I got, it made me feel really hopeful! <3
