I would say that it might be true that one of the P and P bailed out and I'd guess it was the one responsible for the writing. The graphics were amazing, as usual, but a lot of them didn't even have any dialogues (metro and pool) or the texts were missing (shower scene and hidden scene).
It doesn't feel like it's a netorare game anymore. So probably the main writer abandoned the project and the guy responsible for the graphics is still on it and is trying to write now.
Definetely not worth all the wait and I wouldn't recommend other people to pledge again. I know I won't.
