Mental disorders are often considered “invisible illnesses,” as the symptoms aren’t always visible. Illustrator and game developer Nicky Case wanted to shed more light on one of the most common mental illnesses – anxiety. With the launch of their new interactive choose-your-own-adventure style game, “Adventures with Anxiety,” Case shows just how clingy the condition can be – by depicting it as a pet wolf, ready to bite at any moment. Case spoke with Storybench, just a few days after the big launch, to discuss interactive story design and making sure we all get enough sleep.
