Unfortunately not. The biggest addition to the enemies is
the puppet, which is basically a jack-in-the-box type of thing. There's a music box that you have to keep wound by opening up the monitor, switching to the room, and then clicking and holding a button to
slooooowly wind it up. There's a meter on that particular camera that tells you how wound up it is and there's flashing indicators that tell you if it's close to winding down and if it's dangerously close to winding down.
As long as the music box is wound and music is playing, he stays in his box. But if the music box stops, then he
disappears, and you hear "pop goes the weasel" tinkling away distantly. Then, at some (indistinct) point in the near future, he
will jump through the window and kill you, and there's nothing you can do to stop it, unless you happen to make it to 6 am. So, if you're looking at the monitor or have the mask on, it'll pull you out of it, and then
SKREEEEEEEE-
Then, there's foxy. I mentioned before how
there's a big, open doorway on the other side of the desk right in front of you. In the first game, you had to look at foxy with the monitor to keep him from leaving his room, but in the second game,
he stands at the far end of the hallway right in front of you and you have to occasionally shine your flashlight on him or else he jumps into the office and kills you, regardless of whether or not you're wearing the mask. So, you can see why keeping the music box wound is so stressful, since foxy and
other animatronics like to stand in the open hallway
just outside your office. And the reason why it's so scary is because most of the time they don't bumrush your office, they
just kind of stand there. So, you have no choice but to open up the monitor to keep the music box wound while they're standing there. Oh, and your flashlight has a limited battery life. Oh, and also
they can come in through the vents to the left or right of you, so you have to keep an eye on those, too. Some of them give you a warning and you have to throw the mask on really quick, while others don't give you that luxury and you have to be wearing the mask as they enter the office or they'll immediately kill you.
And so the whole dichotomy of what makes the game scary changes. In the first game, it was that you're paranoid that you're going to be eaten by monsters, so you look at the monitor, which drains your power and leaves you vulnerable, which leaves you closer to getting eaten by monsters, which makes you more paranoid, which makes you look at the monitor, which drains your power even more, which leaves you even closer to getting eaten by monsters, which makes you even more paranoid, which makes you check your monitor, which drains even
more power, which leaves you even
closer to getting eaten by monsters, which makes you even
more paranoid, and so on and so forth until
SKREEEEEEEE-
In the second game, you want to put on the mask. You want to put on the mask, but you can't put on the mask, cause you need to look at the monitor, but you can't look at the monitor because there's 11 goddamn monsters to worry about. You look at the monitor, but you can't look at the monitor because you need to shine the flashlight in the hallway and check the vents, but you can't shine the flashlight in the hallway and check the vents because there could be something you missed and you want to put the mask on just to be safe. Then, the warning indicator starts flashing so you know you
need to look at the monitor, but you
can't look at the monitor because there's monsters everywhere, and you
want to freeze them in place with your flashlight but your flashlight has a limited battery. But you
need to wind up the music box, so you
need to look at the monitor. And so on and so forth until
SKREEEEEEE-
So. You can see where the jump in difficulty comes from.
