From the makers of Candy Witch, Witches Brew is a scary little application that shows you spooky Halloween-style scenes like bats flying around a witches' castle, and a bubbling cauldron of objects, such as a skeleton's hand.

The soundtrack includes a distant thunder, a wolf howl and an unidentified growling beast.
