You think they would easily give up chasing you once you've gone far enough? Well, good news for you, it is applicable to Freddy, who, while he has a tendency to give you heart-stopping hunts, does eventually stop if you manage to reach far enough.
Oh, god, every time they start to chase you.
Every time the animatronics spot you and start giving chase.
Meanwhile, Chica's stage is an expansive forest, and yes, there are a lot of trees there. Sure, there are only so many spots where the items can be generated, but it's only doable for small-sized levels with a small number of nooks and edges like Freddy's, which takes place in a house corridor.
And the items have randomized spawn points. That doesn't sound so bad.until you find out that you have to do it within a time limit.
The objective of all levels in the mode requires you to collect items within the location while avoiding the animatronics.
The worst by far, though, are the Fallen Endos, who emit a completely unnatural-sounding, reverberating electronic screech. Everyone has their own unique one, too: Freddy and Bonnie bellow out an angry, guttural roar, while Chica and Foxy emit a horrifying, high-pitched shriek. While the official FNAF games have some pretty effective Jump Scare noises to begin with, this game takes it to a whole new level.
The OST in every single game has a sort of Soundtrack Dissonance and literal dissonance to make it seem creepy.
Unlike most of the official games, where you're fighting the Animatronics because it's your job, in this game you're just some poor sap who gets stalked by the Animatronics in his own house.
They resemble horribly mangled and burned versions of the already dishevelled original animatronics from Five Nights at Freddy's 2 for instance, Freddy (who is actually one of the least messed-up) has no lower jaw or hands.
