Google is celebrating Halloween with a special Doodle - an amusing browser game.
The game seems simple - a player controls a cat that needs to defeat ghosts by drawing the symbol hovering over their heads. But, as the game progresses, the ghosts appear faster, in more numbers and the symbols get more complicated to draw.
The game includes five levels set in school environments: the library, cafeteria, classroom, gym, and the building's rooftop, each with their own boss.
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. 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.
The original concept for the game involved a magic cat making a soup that was so good, it raised the dead. Connecting soup to Halloween proved too abstract, so the team shifted to the idea of a wizard school.
