Telltale said weeks ago that a skeleton crew would be staying with the company to keep things going, as far as their prior obligations were concerned. Narrative designer Rachel Noel was part of that team, but according to a tweet she sent out today, that whole team has been laid off as well. No rhyme or reason for the layoffs were given.
UPDATE - Rachel Noel has updated her statement to say that just her team was laid off, but there are still people at the company. Thanks to PhantomLiger for the heads up!
I think there was some misunderstanding about my earlier message... There are still good people at the company. MY team is done.— Retchel Necronoelicon (@anameformyself) October 4, 2018
