I said only what creators said about routes order
Actually I decided to play Jenna route as the last one as well, but not bc it well closure whole story, but bc i heard that it has "good ending" and I don't want to say goodbye to Echo with the nerve wracking routes like Flynn and TJ :)
I haven't played Jenna yet and I don't realy want to no matter If she realy has A ending, I don't belive anyone will be happy but I will find courage and go through... somehow
