theories in Little Nightmares

i decided to take a look into little nightmares 2`s files, and i found a file thats named: PreOrderDLC, is this a dlc that was canceled?

What if the light at the end of little nightmares one is six waking up

Whait, Is That.... The Pigtail Girl?

its a part of a working DLC?

what you think?

Guys i think there is the dentist boss in LN3

Look at this imagine, i think alone and low are in some kind of office and i think is the dentist office

what you think?

If you listen "the sound of nigthmares" The Workers in the Walls you ear Noone talk about 3 nuns.

maybe they can be some secondary villan of LN3

what you think?
