Celebrate Halloween with a cosmic new Google Doodle, featuring an astronaut cat vanquishing creepy creatures across Earth's atmosphere.

With Halloween just around the corner, Google is embracing the festival spirit and has launched an exciting, revamped Doodle game that brings interactive fun to its homepage.

The Google Doodle team worked for four months on this project, releasing a new series of levels this Halloween including minion and boss fights.

The Great Ghoul Duel's page has some credits, early sketches of the game's new characters, and even the names of the ghosts you play when you embark on your battles.
