I have not entered the game yet, but efforts are evident by the weight. (Perhaps it may sound like something wrong because of the translator, but the good fellow.)

There is a lot of text, which is also expressed in the movement and emotions of the characters. I think there is a text for a small book (But there are images and quite a lot).
I didn’t understand half of the text (I don’t know English very well), but as I understood there are spoilers for both the game and its future.
