Sorry for the late reply -
I was considering scrapping it entirely as I was focusing on growing my youtube channel but around October I started brainstorming ideas and completely started from scratch yet again. Surprisingly I have everything planned out - maps, items, story, endings, and enemies are almost locked in.
I don't want to spoil anything for if I do release it, but it is now a single DLC loosely based on Ao Oni S, and as for the 'tales' DLC, when you play the game the first objective is to find each of your friends. When you find each friend, they are available to use as a partner and can complete their tale, which is a short story on what they did between the game and DLC.
I don't want to set any expectations but maybe towards the end of the year something might appear, maybe.
