This is a game that has a ton of story and strategy elements. You will be splitting half of your time in book mode.
The other half of your time will be spent in battle mode.
Later in the game book mode will also provide other options through the tabs on the right hand side.
As you view the stories in book mode you will come across battles.
The battles appear as map on the pages of the book.
The battles are the real gameplay of the game. As you can see this game is amazingly beautiful.
I'll include a couple captures here so people who don't have the game can at least see what story mode is like.
Then I will mainly skip from battle to battle, describing what you need to do to get through them.
Go ahead and view the next episode. Once you get back to book mode you will see what looks like a map on the page. View the "Encounter at Bruhl" map episode.
