I can get the package to work, but I can't see the bullets. I only see explosions.

I had to add the render feature after the fact. This is probably because I installed and removed the unity package some amount of times to try to get it to render. Once you have URP set up in your project settings, find your "URP_Renderer" object in your Project and look in the Inspector window for "Add Renderer Feature". Add the "Bullet Fury Render Feature" and you're good to go!
