Nice concept! The mechanics work very well, and once you get how the game works, it's fun! The visual style is good, but the child-like cheerfulness doesn't match the gameplay. Could also use some more clarity in-game, that you have to rotate your "units". It wasn't clear which direction the tornado was facing. It would have been nice to use right click or mouse wheel to rotate the objects since the rest of the game is played with the mouse. The ability to skip ahead to the battle would've been nice, too.
