Hello, I worked on a side project aiming to extract the Japanese text out of this game.
It's far from perfect but could be used as a reference until something better is released.
There is a jupyter notebook as well, linked in the main page, that shows some basic analysis over the text using tagging to JLPT levels for kanji/ vocab.
Still, the main point of this work remains the text dump.
The .csv (UTF-8) is in the release section on the right.

Hope it's helpful to somebody who has been playing the game for the purpose of learning more Japanese.
