Hey! Thanks for getting the game! The Chained Panopticon can now be downloaded for free on this page :)
Hope you have fun! If you want to chat about Micro Circuits you can write about it on twitter using the #osr hashtag, the subreddit /osr or the facebook group OSR RPG. These are the places where I've seen people talking about it the most. For extra content, I try to group all fan-made content on this collection here on itch.
