Pro tip, and we forgot to mention this in the rules because big brain: Crouching makes it so the creature can't hear you
Oh dang, that makes sense. I was already wondering why there was a "useless crouch" mechanic in the game.
Heh yep, I forgot to mute the footsteps or make them quieter to let the player know about the mechanic. While crouched it can still see you, but from a much shorter range.
