All visual effects and graphics are not actually done yet. The current build is pre-alpha and only has placeholder meshes (spheres), placeholder materials and textures (plain colors), - ie: it does not have any of the assets in place yet. That we are confident about, but we don't want to implement it just yet until the gameplace has been finalized.
Still interested in trying a pre-alpha build to give some feedback? Otherwise I'd suggest waiting a little longer until we start to implement some of the graphics 😉
