If you’re feeling a bit bored, Google has a new Halloween-themed Doodle to keep you preoccupied. You’ll be playing a game set in the Magic Cat Academy where you play Momo, a cute black cat with magic powers. Your mission is to defeat ghosts that have invaded the school by doodling the symbols that show up on top of the head of the spirits. It can be played on both the browser and mobile devices. It gets kind of addictive if you get into the spirit of it.
