Awesome!
It's always great to see how classic submissions still live up to today's standards! This was fantastic because you just had no idea what was going to happen next. It was also great how the blood contrasted with the black, white, and gray images of everything else. It seems like this took place in a forest or something. The action and transition effects were great as well. It certainly doesn't need a plot, as it's standard stick action!
The music is great too, if it gets a bit repetitive. All the sounds are done in a fairly realistic manner and I like how they sync so well with the animation. The freakiest part was probably when the one guy exploded. You'd think that would finish the guy off, but it goes on for a really good amount of time. I'm not sure what the brown colors are for.
