Thank you for your comment!
Yes, the theme is not really present because I haven't had the time to implement the features that fit the theme. There is an inkwell and a piece of blotting paper in the game because I was planning to make the writing feather dip into the inkwell and make ink splash on the paper that the player would need to clean up with the blotting paper. Unfortunately, I didn't have enough time to add these features.
And yes, the last line is a bug. I didn't have enough time to properly finish the game. I was planning to include a short text describing Elisabeth's reaction after receiving the letter. Her reaction would have changed if the paper had too much ink splash on it, haha.
