This was very much an experiment in building something that talks ActivityPub Server-to-Server. Chess happened to be a fun, not too difficult idea to get the experiment going. (The chess parts are largely built on existing work, such as chess.js and icons from the same set Wikipedia uses.)
Feel free to ask anything!
Someone will probably come along and build a GUI that works with the toots. It would be a neat browser plugin project. Are you planning to open source this?
As for open-sourcing, I'm considering it! I'm probably going to wait a little bit until the dust settles, before deciding.
Take the less-than-production-grade code you find in many hobby projects, add in the tendency of HN to tear to shreds (however well-meaning) any code which gets presented, and open sourcing hobby projects can be a recipe for disaster.
Edit: I'm not saying open source is bad (obviously) or that it's always toxic. But it definitely can be.

I don't think HN is this bad unless the code in question is actively doing harm (e.g. bad crpyto). I'll always be more critical of good closed source software than bad open source software.
By a GUI client, I mean a frontend that you can log in with your Mastodon/Pleroma/AP account in order to play in real time and/or view other players' games. Possibly integratable into AP-compatible clients.
I'm not sure if clients even have functionality to integrate? Most have an 'open in browser' option that I guess could work, but you'd still need a session with the AP provider. (And those APIs probably all differ too!)
