Thanks! With 3D the main challenge might be visualizing the layers separately. Ideally each of the phases would have some kind of metaball effect and also be transparent and even refract. Will be pretty tough to do and will have to fight with uncanny valley effect.

Sometimes for sandbox I feel like 2D can be more fun because people can target particles they interact with better.

Maybe WebXR will be good for the 3D version.
