Sorry for the late reply. The simulation as per the blog post already has gravity. What part are you struggling with?

I actually do have some basic polygon collision code that was working, but I never ended up optimizing it properly and I don't promise that it's correct. It should be...

Ahh! Sorry about that. I've updated the post to include that function.

Isn't `l2` already squared?

A bit of both. You *have* to use them to use Burst, but also they give much more control over allocations which means you should be able to do better...
