I like the story but it can be boring to always come up as "text". If a book always comes across as text and what you're doing is a game, then - even if it's story-based - it should make a difference in telling the story. It doesn't have to make a difference in gameplay, whether the gameplay is mid or sub-mid, but it has to make a difference narratively. If this does not happen, if you make all your texts into a book and add your art to some pages of the book, nothing will change. If you want to tell a story with the game, the main thing is to feed that story into the game. Even if some places had sound instead of text, the effect would have been even greater. Please take this as constructive criticism :)
