Wow. Very fluid animation, I really dig the chalky outlines! Though they were a bit too thin for my taste sometimes when they began to search for the berries[around 1:00-2:45]. That's pretty much the only small criticism I could give you because everything else is really good. The monster that attacked Sprout reminded me a bit of the Pikmin series. The sound effects and music were also superb. Trying something different often results into something good from my experience, in this case it turned into something amazing!
Can't wait for Episode 2!
