Hello, no the demo is SFW (they need to know each other before doing some things :v ). Greyed out means it's deactivated, but you are not the only one, having problem understand it, I will change that in the UI overhaul I plan for the final game!
As for the mailing list, does this link works? https://landing.mailerlite.com/webforms/landing/t8o8z8
Thank you for playing our demo <3
