Amanda,
I very, very nearly quit this game after the opening screen because it was just so heartbreaking. I did set it aside, do some other things, and steel myself before returning.
This is just beautiful. As a game, as a puzzle, as a story, as writing, as a love letter. And, yes, still heartbreaking, but so suffused with beauty and love that the sorrow is worth it. I am so glad I came back to it (though I knew I would, because the writing was so lovely I was not going to be able to stay away).
Thank you for sharing this with the world.
