Are you able to be with all the girls in this or do you stick to one the whole game? Any info is appreciated!
It is full on harem as far as known. There is one decision in EP3 where you have to choose one of two (Skylar has more content for the most part, Jessica has had a big upgrade in EP9). It is currently unknown to the public if there will be a reconciliation later in the game.
All other girls are ok, at least for now.
