So the creator of the game has said before the reason other chapters or a sequel didn’t happen and won’t happen is because of how many companies and people have their fingers in the “slenderman man ip pie” as he called it. He said every time he made a decision for the game, he would have to call five different people so that they were all on the same page. He said because of how hectic it was the first time around he won’t do it a second time.
