Make a game in Lisp in 10 days. Guidelines and a HUGE crowdsourced list of resources/libraries are on the current jam page.
EDITED changed 7 to 10
EDITED remove link to old jam page
Is it 10 (as the overview says) or 7 (as stated here) days?
Sorry, ten :)
Hey there! I have a quick list of resources about Racket, a Lisp you don't seem to have listed in the Overview:
Racket used to be a Scheme, but has since grown into its own language with lots of modern features: http://racket-lang.org/
Examples of games written in Racket: http://docs.racket-lang.org/games/
Realm of Racket is a book where you learn Racket by making games: https://www.nostarch.com/realmofracket
Jay McCarthy's Get Bonus! system is an example of doing SNES-inspired game development in Racket: https://github.com/get-bonus/get-bonus. Watch the RacketCon video for an idea of how it works:
Neil Toronto's Pict3D library lets you build interactive 3D scenes right in DrRacket: https://docs.racket-lang.org/pict3d/index.html. There's a video for it too, but it's less focused on games:
