Them visual! love the animation and the idea behind it. Making the elements work with each other at the beginning as a test is pretty darn neat. Great job overall, nice movement, nice looks, nice mechanics. Oh and the CALM integration is pretty darn slick! The one thing I would like is to have seen was a sort of "tempest" creature, it would've add a little "oh this is what I'm fighting". Perhaps there was one if I didn't get killed constantly lol!
Oh and the Slowdown mechanic is really nice, love the visual concept for it too.
