Fennel absolutely rocks for creating games. It integrates with TIC-80 (open source fantasy console) and also Love (game engine) and PICO-8. Lots of blog articles on getting started. Check it out!
Can't say I made anything worth mentioning. There are some bigger templates available that I am sure do more useful things, but I prefer something small enough that I can see what is going on.
Worked fine even for getting things to run in LoveDOS, a port of some older Love2D version to MS-DOS. In practice compilation was a bit too slow for comfort, so a better way was to pre-compile the fennel-scripts to Lua and just run those.
I installed some LSP server for fennel that comes with optional built-in code completion for both Love2D and TIC-80. Works well in emacs.
