Sweet stuff, Kirb!
I'm really starting to like the videos you make now, they're getting FAR more sophisticated than your previous works, and just overall making improvement. That, and you have lots of different voice actors working with you too. Writing is pretty good; I like the way the conversation between Rockoon and Doubling moves along, and the way it progresses.
OVERALL, I give you a 4/5 and a 9/10 for sophistication. If I were to suggest anything to improve on, it would be the writing. Then again, not everything's meant to be perfect; I don't wanna make you groom the series, so I'll except what it is and pass it off.
