Press "E" when you're behind the enemies, then you should make them "sleep", using your first spell. After this, do the same thing with the second skill to transform yourself into them, so they will stop try to kill you.
Sorry for this. Actually, this game was made for a game jam, and due some time problems, I've writed the controls and tips just on the submission post. But I have plans to made this a real and complete game.
