I added basic matchmaking functionality to Cooperative Chess. You can now indicate your desire to play in a temporary room with another player in any of the default (Easy, Normal, or Hard) difficulties. On a related but different note, I find that I typically play Co-op Chess with voice over discord, and in doing so realize that there are certain types of information that I find it's more fun when I convey it (things like "I think we can bonus" or "I see checkmate"). I want to know if players want a feature with canned phrases like this, so I posted a question in the Cooperative Chess discussion forum. Any feedback there would be appreciated. Thanks!
