So... renders seem nice. Is the story good? Can we bang pretty much everyone?
The story is interesting, and well written, but it doesn't have a very deep nor complicated plot.
Yes, you can pretty much bang everyone. There are some choices, and a handful of them do influence the story and the side-stories to a great extend, but mostly it's just to determine which kinks you want to explore and which ones you want to avoid.
That said however, the game is pretty good, has some great animations and beautiful renders and I'm having a blast with the storylines so I would certainly recommend the game. As I mentioned, most kinks can be chosen/avoided, but some of those choices do lock you out of a certain girl's path. So keep that in mind.
