I have just played the game, and I have enjoyed the mix of humor and dark side. And the breaking of the fourth wall.
I don´t believe that Karma just impact in being in the + o - side. I have 4 playtroughts, one freestyle (sure in Karma+) and another angelical and there are diferences. And have another 2, evil and really evil, and there are also diferencies.
But I don´t see the point of the developer of making two games at the same time. Obviously, it´s her time and her effort, and so her decision and I´m sure she have her reasons, but the result it´s having two games with long time between updates, making more difficult for the game to get traction. Unles she gets a creative block in the first one (and I don´t believe that it´s the case, the story seems strong enought to be well thought from the start) I don´t see the point of it.
