Really impressive animations and many lovely monster designs. My main criticism, in terms of game design, would be giving the playing more health or something to that affect, as I thought having the player be a one-hit-kill in their normal state along with being very slow, made the game unnecessarily difficult.
Taking control of other creatures is definitely a good concept and all of the art and vibe of the game help support that and what you ended up with by the deadline is very cool. Nice work! :)
