idea what if the entitys worked at the company with you like their all some form of science project to send them in to guard the backrooms
every time you fail 3 times to a entity it becomes a permanit entity meaning example if you failed to the smiler 3 times her smile would change to another color at random showing shes not the girl at the officer with you now and when they mate you they might even say something like i missed staring at you after i won so many times i was forced to stay here and now i cant leave
sorta like you doom them for your failures
you could even have a database of all the entitys you fail to and if your not caught by one for x amount of days their naughty value will rise to a point were when they get you they might be very aggressive pinning you against the wall and forcing it out of you
more passive entitys would be much more sneaky but full on thirsty entitys will run like a wolf and have a really loud audio
basicly they have high speed high detection and are really loud as their a huge danger to your survival
more passive and tamed entittys might be slower but more sneaky and when they claim you they will be more flirty and soft to you
with the officer entitys being always their normal selfs
