Very sweet and evocative narrative, I'm amazed you managed to breath so much life into a text-based game! The soft music definitely did help build the mood as well.
I would suggest spending some more time on the UI experience, especially as a wholly UI-based game. Formatting the text more centrally with the choices appearing in a different font, perhaps slightly after the text appeared could have added a lot to the eperience.
There's also, of course, many more optons such as adding some basic sound effects to mark specific moments in the narrative or using some interesting text formatting or typing-out effects to help build the suspense and power of certain moments.
But that said the narrative was strong making the experience really enjoyable!
