This concept art really scared me because it looks like the ball in the middle is going to envelope the world that is in. It would be cool if the ball inside the structure creative mode zombies and continuously did so until the world was destroyed in game logic until the heroes anti Heroes saved the day.
Art style reference. I'm already going for a simplistic style for my game, but this gave me the idea of using a limited colour palette, and defining each characters silhouette to make them more distinguishable. (((So Furious)))
