The game looks really good so far and promissing, but like everybody said, It needs some stuff fixed.
Here's the list of things I noticed.
The most obvious: The light.
It's SO DARK, and the neon lights are way too bright. Maybe make It a little less dark, but put light switches in the rooms as an option. I know, It sounds against the rules of a FNAF game, but just a proposition.
The animations, some have a short duration, like Frederica's doggystyle, I don't know if It's because I clicked somewhere, but It seems to only last a few seconds.
But then Bonnie (or Bunny, like in the game), the animations last way too long.
Perhaps make a small menu to change between animation variations according to the position, and an exit button, in case players want to check another character, before 6AM.
Also, a small crosshair in the POV when you're wandering around.
Now for something that kinda disturbed me...
When I finally found out which key was the flashlight, I could not wait to see the new models, cause It was so dark even during the sex scenes I couldn't figure out any features.
So I reached 3AM, I ran out of the office and flashlight in hand to see the new sexy models!
And... their faces... are so disturbing! I would say It's the teeth, but It was definitely those black marks across their faces.
I don't know what's with It, but It makes them look way too creepier than sexier. I say maybe remove those marks, maybe...
ONE THING I MUST GIVE YOU CREDIT FOR IS choosing models with actual feet instead of those ugly mechanical feet like the older models of early FNAF 3D porn.
And those glowing eyes, oh man, they're so sexy and menacing! Keep those!
Overall, keep It up, and I leave my suggestions.
