Wow, first thread around here in a long time.
Anyway, I'm a little irked about how all craters are slightly oval. It just looks... weird, especially for head-on collisions.
What if craters were circular for Head On's, stretched ellipses for Angled's, and scar-shaped for Shavers? All with scraggly edges, of course. I'm especially enthusiastic about the Shavers fix, since several sam-size overlapping craters looks hecka ugly
