Phil Hagelberg recently won the Lisp Game Jam 2018 with his entry EXO_encounter 667. What I found most interesting however, was his interactive programming setup. He programmed his game in (and contributed new features to) a Lisp to Lua compiler called Fennel, and used the game programming library Löve. With Emacs and some Lua thread magic, he was able to perform runtime changes and introspection to his live running game project. (See below for a demo!)
