Blast Ghosts And Even The Haunted Sun With This Year’s Halloween Google Doodle

Google is celebrating Halloween with a brand new installment of Magic Cat Academy–marking the third edition of the Doodle. In the past, Momo the cat has taken on ghouls in school and taken a deep dive to tackle sea monsters. This year, Google pits Momo against ghosts and space creatures as she battles her arch nemesis, Marshmallow the ghost, across the cosmos.

The rules of the game are simple: Draw the designated lines to defeat ghosts and other monsters across five stages. The lines and their sequence get more difficult as the game progresses, but you can always draw a heart to get more life, you just have to be quick.

After every level, there’s a small scientific fact about the level of the atmosphere and something that the level focused on like stars or the flying fox bat. Google even included a gallery of concept art ranging from level design to dropped ideas like Momo and Marshmallow becoming a giant mech and teaming up. There’s also a photo of the real-life Momo lounging around.

The game will run through October 31, 11:59 PM ET. You can also learn more about this Doodle, Momo’s other adventures, and past Doodles here.
