As someone with several chronic illness(one of which caused me to have to quit my job), this game really resonated with me. The pushing through the pain, trying to live a normal life. The fear of it's growth, worried how much more of you it will take. The isolation it brings you, your connections severing in it's claws from it's grasp. The hopelessness that shadows you, never being able to see a way out. The connection, finding help and comfort when you feel like you don't deserve it. The relief of treatment, it's not gone, but manageable again. Working towards coexistence as you curse it, because neither of you ask for this union, but you're here none the less.
This is definitely a game I'll send to people to help them understand what it's like to live with chronic conditions.
