There are some new animations, as well as the showers now that heal up your health. (The showers are at each save point)
In terms of animations that are new I only found 2 new H animations, but I could have missed some. One is not really a full H, but the remote controlled car pokes her in the butt, I can't find any other use of it, I am sure it should do something later?
The other new one is with the ceiling tentacle, it has now an internal view.
It does indeed end at Yellow card. Though I didn't manage to find the green card? But I guess yellow is before green or?
