I've linked a few video demos on the GitHub readme, and there is a playable demo on my website.

Using WebGPU has been great so far. The iteration loop (with Vite.js) is much faster than when working with Unity. This helps with quick prototyping, though Unity's editor scripts allow you to build more interesting user input tools.

I was also surprised by how good the WebGPU error logs were. They helped me debug most of my shader bugs pretty quickly.
