Google's periodic doodle things on their homepage are usually annoying, but today's Halloween game, which they revived from a few years ago, is super simple and super fun.

Nothing groundbreaking, but if you haven't tried it you're missing out on a few minutes of fun. Just go to Google and click the play button on the screen to load it up. You only need a mouse/mousepad to play.

This game is way easier if you play it on a phone or tablet, and you can whoop enemies faster if you have a touch screen pen.

The strategy is to draw the shapes as small as possible so you get them done quicker, and look out for certain shapes (like the purple swirl or heart) which, respectively, damage all enemies on screen and refill your health.
