I don't know if there's a difference in the gaming for supporters and non-supporters-yet, but two things: There are really few images. I have been watching the very same picture of the same character for a while during the library sequence while other images of her with different attitudes or emotions could be more interesting than only her reddened cheeks. They are not synchronized with the text like when she starts undressing herself... and here is my second point.
She starts undressing herself... Okay... But the picture is empty of any text or option, and even if I click my mouse anywhere on the game screen, nothing happens and that very same image of her with her hands on the top of her shirt is the last thing I have. I don't know if it is already the end of the game or if I am not allowed to go any further. But if it is possible to continue the story, I don't have a clue about how to do it. If it is already the end, it is bizarre.
I wonder how you got those marks. I'm afraid this is the only mark I can give for a game I find a bit empty, a bit boring (not very challenging), and buggy.
