Hi all, I documented a minimal Fennel setup to use Raylib here: https://github.com/dawranliou/minimal-raylib-fennel. This setup uses the Luajit-based binding from the raylib-lua project. With a little tinkering, I was utterly amazed at how little needed to be done to integrate Fennel. Kudos to the Fennel's maintainers and the community!
I don't know if I'll use this setup for my game jam entry this time or stick with the tried-and-true alexjgriffith/min-love2d-fennel. We'll see! However, feel free to submit issues or your feedback. Thanks!
