Katey (who is a kid witch by the way) has new magical abilities, and she also has a new ally with her, a slightly older witch called Sheridan. You can flick between the two witches at any time and use their different powers to get through the level. Katey is smaller, and can fit under some gaps that Sheridan can't. Sheridan can hop over gaps though. Katey can throw ingredients into a cauldron and cast spells, but if Sheridan tries it will backfire on her. Sheridan's main advantage is that her fire magic can be used on some monsters to attack.
