The Screamer

In-Game Behavior
The Screamer initially spawns in a harmless state as she wanders around the map without doing anything that could hurt anyone. If anyone enters her view and gets close enough, The Screamer will attack players with a close-range jumpscare. If The Screamer is bothered at least 3 times, she'll eventually become upset and start going on a rampage! Immediately after coming into a new state, The Screamer will use another jumpscare attack that affects a wide area around herself; she'll use this attack again every 15-20 seconds. Only after the first time this attack is used however, The Screamer will turn the walls of the level into a threat! Touching the walls after The Screamer has become provoked will deal you constant small damage. While provoked, The Screamer's movement speed is rapidly changing; every now and then she'll increase or decrease in speed, and there's no pattern that makes it predictable either. To attack, The Screamer first slashes the opponent and knocks them over, then she'll pounce them leaving them stuck to die. All of The Screamer's direct attacks deal heavy damage.

Trivia

 * The walls hurting you while The Screamer is in her provoked state is a reference to not being able to touch the walls in Scary Maze Game, since you'd lose if you did.
