I once made a boid-thingy, which this also reminds me of. https://matsemann.github.io/boids-workshop/ (and since the parent game is mostly boid behavior with a goal condition, I guess that's why the LLM is so successful in implementing it?)

The link is the final result with lots of controls, but the idea is that it's a tutorial/workshop where you build it step by step yourself, in Norwegian though https://github.com/Matsemann/boids-workshop
