That's quite creepy actually...
Well gotta say that is creepy, but I'm into creepy, and this actually made me chuckle a tad. How'd you make the voice?
The voice is straight from Mario Teaches Typing. In that "game," there's a disembodied Mario head guiding you on how to play the game, as well as occasionally providing clever little quips and lame jokes.
As for the animation, it's pretty good. I'd say it works perfectly!
