This update is almost non-existent.. I mean I guess the last update was a bit of time ago, but that Update also didn't exactly do much either.
The good thing I can see is that the sister storyline does progress, which is nice, but I went though this content in 10-15 minutes flat, the only issue was that there was an issue with getting the content to activate initially and afterwards the instructions for how to proceed also didn't exactly match the stage at which you were on. The BJ is nice, but that's it.
But I guess that's that. The game has a bit of extra content but that's all. Sister is hot, but it just felt like it was a rushed update considering that some of the images were completely missing where they clearly should be present (Instead of the previous concept art for the future scenes, it is just an empty screen and a bit of text to explain what's happening).
