Call me when they remove the horrible filter that ruins the game graphics
There's a GDC panel onlne about their approach to the art design for the game and how they implement it with their tools, and I cringed when they showed how they applied the filter to the whole image and you see what it does to the backgrounds.
Also, this "rumor" does not deserve the attention as there's no credible proof any of it is real, and is not just piggybacking on existing speculation.
