There's actually MINIMAL animation there - almost none. But the drawings and style are superb - reminds me of THE INCREDIBLES a bit.
Almost like a more advanced version of a storyboard/animatic.
ALSO makes me think of the art of the old Lucasarts adventures, which I LOVE! (Day of the Tentacle, Indiana Jones and the Fate of Atlantis, Sam & Max: Hit the Road, etc...)
that was well done. No dialogue, just images to move the plot along. Clean, well drawn, nicely animated. The minimalism was appropriate. Good use of music too, btw.
