Just played it last night, and while I think it's pretty neat, I do have some feedback.
Firstly, it's honestly pretty difficult to figure out where you need to go and what your next objective should be. The 'objective' tracker only ever says 'explore the complex', and gives no clue what your next goal should be. There's also no real direction as to where you should go. While having most doors clearly labeled is very helpful, when some of those doors are three and four rooms away from the main hall, it can be a lot of random wandering around to figure out where things are. A simple static map giving the general layout of the main rooms would go a long way towards making navigation much easier.
It's also difficult to keep track of what you do and don't have access to without just trying every door you come across, resulting in having to go through multiple loading pauses before finding the room you need. Far as I can tell, there isn't any inventory screen where you can see which keycards or items you currently have, meaning unless you're taking notes, trying every door is your only real option.
I was also a bit disappointed with the futa mode. It's nice that it's there for those of us that enjoy it, but it was kinda lackluster. Doesn't change of influence the sex scenes, and doesn't even come up unless you do get into a sex scene. I was kinda hoping the animatronics would have their dongs out while chasing you, or at least in the character viewer, but sadly it doesn't really do much. I understand making it change sex scenes requires making additional animations, which takes time, so I'm not expecting any big changes anytime soon, but it would be nice to know if it's something planned in the future. Maybe give it the option to let the girls be the tops in this case, which I think at least some of the players might appreciate.
All in all, it's a good start, and I can see this game becoming a lot better down the road. Hope to see more updates in the future.
