Muahaha!
Brilliant, man! I loved this flash. The voice acting was probably the best part. And art was... well.. I don't think it was supposed to be artsy-ish... er.. ehem, the animation was simple, but well done and fitting. In the end, I found that I laughed through most of it. In fact, I'm listening to it as I write this review, and I'm still laughing.
Oh, on another note, it was pissing me off that I couldn't remember where I've heard that opening credits song. Read the credits though and felt incredibly relieved. Now, if you'll excuse me, I'm going to go watch Advent Children again. Good job man.
