Don't judge by lack of sound alone
Okay, I'm going to admit right now that I am kind of frustrated by how this doesn't have any sound. It seems like you could simply place a popular high paced song over it to have more people enjoy it. I still found this to be enjoyable because the animation is actually really good in this. What's also funny is the random appearance by Gordon Freeman not as a stick figure. I guess the lack of sound makes it hard for you to figure out the story. It's still fun to watch.
I think my favorite would probably be the stick figures who have the white masks. Apart from said masks, they have the coolest weapons. Freeman looks great as a stick figure in this. The animation moves quite fluidly and gives off a nice sense of action. You really don't know what to expect from the random location of New Mexico in the beginning.
Love the soundtrack.
You needa soundtrack also im not too big on your graphics. Just sayin.
HOW THE FUCK DID YOU DO THIS ON PIVOT?! AMAZING!
You can make it better with a story.
Looks really really good, and I beat your tired of hearing this but *cough* Sound is a must!
