Clean visuals and decent music, but for how short the game is, it's pretty glitchy. I liked killing humans (don't quote this, please), and I think you could make this game really awesome - getting some lemming vibes here - but the game is so easy and so short, that it feels like it's over before it even began. I also realized pretty late that you only need a handful of guys to get through to win, and I just kind of got a perfect "kill one or two guys in each level" on accident. I had a screnshot of what happens if you move the wall-climbing green bit into the little guys, and they went absolutely insane - clipping through the ceiling, into the walls, etc. Still, it's an interesting gimmick, very in line with the theme - much more than my entry, that's for sure.
