I admit that I love this as much as everyone else. I think its biggest strength is how good the animation is. I didn't even think the guys in the meat place were that bad at first. They really do seem to be more evil when the shadowed boss appeared. Shadowed bosses are always trouble. The voice acting is great too.
I would love to see where this goes. It doesn't have much of a story to continue, but I don't care. I liked how he was willing to spare the other people after he killed the boss. Of course, they could have all just died when he blew the place up. This is truly an original idea. You deserve all the praise.
