How do I know when Freddy is going to attack?
She doesn’t make any noise when she’s at the door
And I think you should be able to see the shadow of Bonnie when she’s at the door and you use the light
when freddy is active, it will always attack 20 seconds or so after 5am. It just attack once, independently of dificulty level.
you actually can see Bonnie's shadow. There is a 2d drawing of a head with eyes at the bottom right corner of the left window when you turn the left light on. if Bonnie is there, its shadow hide that drawing.
