This is probably way too glowy.  It’s still using the glowy vector shader that’s standard in VectorStorm games;  it works nicely to oversaturate the bright spots, but just looks blurry over in the darker areas.  It should be pretty trivial to modify the shader into a proper bloom which affects bright areas without affecting darker regions of the screen.

But I do like how it adds extra colours into the scene, to be drawing ground as extruded cubes, and be able to put a different colour on the tops than on the sides.
