Extremely great and promising game! I played this before the update so what I have to say may not be relevant but I think it still should be since I'm avoiding bugs.
Actually I will say that there was a bug that softlocks you when you close the door right as you get caught by an animatronic, specifically bonnie. This might be in the new update which is why I'm mentioning it.
Anyways, the concept of a free-roam horror nsfw game is something I've been looking for forever. The fact that it's fnaf only makes it better imo. Immediately the concept alone makes this game one of my top 10 nsfw games of all time. It is a bit too dark which makes it hard to see, but that may be what you're going for.
However, if I were you I would lean less into the scary since that's not what players are playing the game for. Replace jumpscare noises with something less scary, like the noises the FNIA characters make when they catch the player. If you're going for a more 'thriller' experience though, do what you want. I'm not your dad.
What I will say is ditch the night system, or at least rework it. Tasks can be beaten before any of the anamitronics even begin moving, meaning you just hide somewhere for the remainder of the game, which means about 5 minutes of doing nothing. It's bad game design to have such a long time of no action. This can be solved by removing night system. Just give the player 3-5 tasks, then let them go back to the exit and end the night immediately.
If you must have a night system, I suggest giving the player tasks over the course of the entire night. Like 1 at the beginning, 1 at midnight or 1 am, and 1 at 3 or 4 am. Also allow the player to leave at 6 am.
I also think animatronics should be more forgiving. Maybe give the player a chance to escape if caught if they have enough sanity, similar to how the illusions work? The reason why instadeath works in other freeroams, say Security Breach, is because there is either a ton of room to escape when seen and/or well as enough lighting to see where to go. This game has neither, meaning instadeath is really unforgiving when there are times where you either have no room to escape or can't see the animatronic right in front of you.
Finally, for the nsfw stuff, the way you handle it is great. I would say don't focus too much on the nsfw stuff, but honestly that's probably what everyone is coming for. I don't think anyone will complain if you give each character a second or even third animation, but honestly even just leaving it at a single animation per animatronic is enough to make people interested. That being said, make sure the main four animatronics are the only ones you add. Any more and the game will get too cluttered without a major redesign.
Again great game. I'm excited to see what you will do in the future. Let me know if you liked my advice or if it doesn't fit your vision.
