Langjam-Gamejam Devlog: Making a Language, Compiler, Vm and 5 Games in 52 Hours
Key topics
The coding community is abuzz with the latest Langjam-Gamejam devlog, where a developer created a language, compiler, VM, and five games in just 52 hours, sparking awe and curiosity. Commenters are marveling at the project's scope and complexity, with some predicting that such jams will continue to push the boundaries of what's possible, potentially leading to the creation of entire operating systems or languages from scratch in the near future. The developer, syn-nine, shares insights into their new language, garlang, revealing a unique blend of FORTH and x86 assembly influences that simplifies handling multiple return values from functions. As commenters explore the project and its possibilities, they're already speculating about the potential for garlang to become a stable, game-dev-friendly language.

I imagine we're 5 years away of "Make your own OS, language, compiler, VM and game in 12 minutes, 36 seconds. Extra points if you gave yourself a stroke."
Create a simulation of a universe with arbitrary physical laws, have it evolve sentient life, and submit the first video game they develop which matches the theme. The theme this year is "rotations". You have 48 hours. Go.
edit: in before anyone asks: no AI was used at all in this project.
It could use some cleanup though as the speed of the jam left little time to think about doing things in a sustainable way. I'm not sure I like the var keyword as I typically prefer to be explicit about types.
It really turned out pretty powerful though and I think it could be really useful as a library for game scripting.

The first year I spent six hours writing one of the first ecs crates in Rust and then an hour turning it into a game. lots of fun! you can search “7HRL” on github to find the historical participants not too ashamed to publicize their code at the end. A few dozen people enjoyed this.
