Just to balance out the feedback. 1) That font was plenty large. I don't see how it could have reasonably been larger without being comical. 2) It seemed kind of self-evident what a playground was. 3) Your voice was plenty loud. I don't know what he was referring to re: mumbling. 4) Not sure what he's looking for there.

In short, I think the video was incredible. I wouldn't change a thing. Thanks for sharing, and don't dwell too much on one user's feedback :)
