Huh.
My first thought was "This is hilariously bad animation," mostly because the stickmen were constantly moving like jellyfish. Then after seeing the white guy punch the green one, listening to sound effects, watching explosions etc. I realized that this is actually really good. I don't know if you tried to make the stick men move all the time, but it was really funny. The sound effects were great... it's funny how sound effects go out of style, but it's true. These reminded me of the good ol' days with Defend Your Castle and such. The "Yes!" noise was awesome too. It was simple animation, but it worked just fine. All in all, I really liked it. I also cracked up when the pink guy walked up with the "Boss" tag... all he really had was some dynamite, and he killed himself. Sorry, this is long... in a nutshell, it was great and I hope you make more.
