Ah OK thank you so much :D Yes I guess I just hadn't realised the chapter breaks.
One other thing I noticed is - I live in the Ch 2 location in the game and the signs in the game for the bus stops is aligned wrong (should look like an H not an I, unless this was intentional). It was the only thing that jumped out to me because otherwise the representation (signs and everything) was spot on! And gave me a great chance to practice my language while playing a game :)
