This was stunning!!! The way the story is laid out was so well done. I thought the "stay warm"/big lightbulb parts were well balanced and were a good set up and gameplay loop that you used so effectively. I forgot to talk about this in my video, but I often think about gameplay loops and how to kind of "weaponize" them against the player and I think you did that here really well. You set something up for us to do and then used those familiar expectations to subvert them. Easier said than done and you did a really good job of it here!
The music was really good, the art was beautiful. That cover shot of her looking at the aurora literally rendered me speechless when I saw it in context. What a beautiful moment.
I think gameplay wise the only thing I didn't love was the way the text jumped forward sometimes. I know it's a good tool for cutting someone off, or for flow of conversation. But I felt bad I was missing stuff and I felt a little silly I couldn't read that fast. I think there's visual indicators like a "But -!" that can showcase that same story beat while being more accessible for slow readers.
Really great job! Heart wrenching, well written, well executed.
