Why does this game not follow the rules of the board game? – Legends of Andor Review

So, there’s lots to like about the game. The graphics and game play seem to work well, after a bit of figuring out time. What I don’t understand is why this game deviates from the rules of the actual board game. What I mean is, in the board game (if I’m understanding THAT correctly) you only progress up the letters once all the heroes have finished a full day (by clicking the rooster button). Here, it seems that it progresses much more quickly. Why change that?! What was wrong with the original game rules?
