Played the demo — this is by far and away the best FNAF NSFW project I've seen! I was really impressed by the UI, and even the little things like the writing scratch when starting a new save or the small details off to the side on the camera screen. Those parts go a long way to making a game feel a lot better to actually boot up and play, and oft neglected in NSFW games.
It almost goes without saying that the models and environment are superb. The only thing I can think of that needs improvement is the detail on the mask and the animation of when the girls show up in the office while you have the mask on (and maybe, if I'm nitpicky, some textures when the girls get close/the fidelity of the models when they slide across the screen while you've got the mask on).
But other than that, I have nothing but positive things to say about this demo. I've routinely been disappointed by other projects of this sort, and even discounting my lowered expectations, I was super impressed. Really great stuff, will be keeping a close eye for when the full thing releases!
