The character handling and sound design were pretty good. Things were responsive. I do think there should have been an introduction of mechanics, or I missed something, as it took me a little bit to figure out the sign.
I've got mixed feelings on the art. While I've seen the art style before (though haven't played a game with it), I was a little soured on it when I attempted to walk across a platform that I thought stretched across a tree, plummeting to my death because it didn't, with no way to know because it's all pitch black on black, the spot in question is in one of the screenshots.
