This is Google's new doodle for Halloween, a spell-casting game which originally was about a magic cat making a soup.

The browser game takes place in five levels set in a school environment which draws inspiration from Harry Potter: the schools' library, cafeteria, a classroom, gym and rooftop, each with their own boss.

A more complicated (and faster) series of symbols awaits the gamer who progresses in the game.

"The inspiration for this year’s cat spell-casting game came from a real-life black cat named Momo that belongs to Doodler Juliana Chen," Google explained in a post.

"It seemed like a good opportunity for a cat hero, since the winner of last year’s Candy Cup Doodle was Yellow Witch and her black cat."

Have a purrfect Halloween!
