Octagon plays like some kind of inverted, first-person Super Hexagon, only with eight sides, not six.
It's a dizzying, twitchy dodge-'em-up that will have you swerving, sliding, and flipping your way - every which way - through a maze of platforms, without falling off the edge.
Formerly an iOS exclusive that hit the App Store last November, Octagon is now available for free on Android devices.
It's the kind of game that can be tough by level two, if you're not quick to catch on to the controls.
If that's your thing, head on over to Google Play and give it a download.
