Before the night starts, you can set the difficulty of the trolls before going into it. Press the Challenges button or just press C to cycle through pre-set challenges. Press the Page button or just press P to reveal the other page of trolls you'll need to endure. To begin, click the BEGIN button or press space. During the night, you must go through different cameras by either clicking them or pressing the number keys. You must also purify the oxygen, which is located in Camera 5. Either click the button or press P. For the MINIGAMEEEEEEEEEE, don't touch the monster! He creeps towards you whenever you touch the sticks or the blue orb. The blue orb is what you need to collect. If the monster touches it, see if you can spot him before he resumes writhing in pain. The orb will creep towards you until collected.
