Very cool!
It is always interesting to look at meta-fictional stuff that takes place in Flash Player itself, but this was one of the best! This is really cool because there's a very creative fight scene at the end in which Red actually gets to show some action. The animation (especially the smashing into walls) was just flawless. The fact that the stick fight had such bizarre things like the different parts of Red's body fighting him. While not as good as say, "Animator Vs. Animation" still an instant classic. I was able to figure about HFS stood for Holy F*cking Sh*t.
