Thanks for your detailed feedback!
She doesnt have any teleport ability instead she can follow player around silently if she could able to see you close by without you looking at her... she is quit good at keep her self out of site thats how the ai is built to spook player. because some times as in early developement if you manage to stuck her ... you wont see her coming at you for the entire game...
I will put her feet sounds and tweak the AI a bit more so player could know or atleast get hints of her following you in the future releases.
