Edutainment! Yay!
I liked the quirky nature of the short, and it was educational; can't argue with that. Ben sounded a bit like Cartman, and that of course made me smile. The graphics and style, also, were fine. I'd say "make 'em better," but that comes with time.
On the constructive side, the voice acting could use work, but it's not a huge thing; I understand it was more a project. The voice quality was scratchy sometimes; if you're using a computer mike, then holding a notecard up in front of the mike can get rid of a lot of the distortion.
Otherwise, kind of a cute little bit of learning. Thanks.
