id maybe suggest focusing on frennis sorta stuff like jumping into her being a manager maybe she leads the other girls a simple voice line for her to tell the girls your in the vents or maybe she hears from chica or foxy that your hiding under a table
id personally love to see them work as a pack seeing theres no game over this could be a great idea if you also used the idea that all of them dont have night vision and work off the same vision we have maybe with a flashlight on their chests or something
you could hide right in front of them and as long as you dont get into their lights your safe but if you alert one of the girls and they dont get you they will warn freni to your last location and in turn she will you the stuidos pa system to tell the others where you last were maybe even mocking the player saying their gonna find you
also if you get caught by all of them being say 5 meters away from the player maybe a screen could play where the pc is sitting on a chair well they each take their own turns on you
another idea is to let the player tame the girls like instead of running maybe if you walk towards them they calm down and start walking up to you if you walk straight up to a girl she will stop right in front of the player and stare into your eyes at which point if the player press interact on them his hand will goto her hip as he says to them how about we fuck babe
after they have sex their bar will go into the green max to make them happy
but if your running it still increases just alot slower with it maybe only going up 25%
but the negitive to lets fuck is your bag instead of being a single clickable where ever you fucked the girls is where your items are spread out
like the idea of saying fuck my clothing i want to fuck now but instead with your items
