The flavor of it is wonderfully crafted! I like the details of faded text switching, translator attribution, and parchment menus. The background images add a lot to the mood, perhaps they can be randomized for each session to add replayability? The music fits very well and the game doesn't feel in need of sound effects.
The page showing the final poem has a bit of weird formatting with the square brackets that doesn't feel entirely poetic. Some of the options that are offered are more fragmentary than others, which certainly fits the tone, but they should probably be given at points where the player picked a either a blank or a different fragment with no punctuation.
This game offers a nice atmospheric experience, and definitely evokes a bit of a sentimental sense of longing.
