Broadly: Still forging ahead building a game server framework in Erlang. I've shifted my attention away from Godot integration (which AFAIK is still working) and toward LÖVE and Lua. Godot is great, but having to write GDScript on the client and Erlang on the backend has caused me many headaches in my game logic. My current goal is to have a beautiful, concurrent, Erlang-based control plane with Lua-based game logic running on both the server and the client.
To that end, I've most recently been hacking on Robert Virding's Luerl (https://github.com/rvirding/luerl), working to adapt the Lua test suite to chase down some small compatibility issues between PUC Lua and Luerl. While Lua is a lovely language, it would also be swell to get Fennel working under Luerl. I wrote a game for the LÖVE jam a few months ago in Fennel and it was a pleasant way to dip my toes into lisp-likes.
I've also been adding things to control plane software, Overworld, here and there: https://github.com/saltysystems/overworld Happily all of the Protobuf and ENet stuff that I've already built nicely carries over into the LÖVE world.
