How to keep yourself from dying in Lunch Lady, and win every match.
How It’s Done
The strategy is quite simple, to become invincible all you have to do is walk inside of an opened door before she sees you, and stand in the middle of it. She can not see or attack you if you are inside the door (pictured below):
After you’re inside of the door, you just wait for her to walk away and you can leave and continue exploring the map! You can crouch and jump while standing inside the door, just do not move.
Pressing shift while inside the door will hold her attention to you until she screams and runs to a teammate.
I hope this helped!
