Episode 6 was about jumping from one girl to the next and little / nothing to do with the main story. I found that to be frustrating. The best AVN's have adult scenes that complement the story, not be the main focus. I hope that changes in Episode 7.
Episodes 1-5 had a good balance because it kept the main story in focus and moving forward. While Episode 6 lost its way, the game isn't unsalvageable. Episode 7 will be telling as to whether it becomes a meh porn game or whether it goes the story-first route and gets back on the right path.
The dev was up front about that, as I recall, at least with respect to the AVNs with cameos in this one. 6 had more set-up than reveal, but just because Riley tells you nothing and Shelby's dad reveals nothing doesn't mean nothing was put in place. As an old guy, the presentation methods can be a little jarring to me, too, but that does not make them bad, it makes me old. Roll with the story as it is told, and enjoy.
My issue with 6 is that it didn't have much in the way of set-up and even less in reveal. 6 was just a series of porn scenes with not much else. It's akin to fan service. I was rolling with the story up until 6, but 6 had no story to enjoy. Episodes 1-5 were good. 6 was a step in the wrong direction.
