The game is updating, just an artist dropped out of the project, the rest is done. They confirmed it on DA.

An artist has not dropped out of the project. The art has been taking a while since the artist is not solely focusing on the project and there is quite a bit of art that needs to be made, but they have not dropped out of the project.
Also, only up to Chapter 2 is currently done, with slight progress on Chapter 3. It's only Chapter 1 and 2 that is done, aside from the art.
