Twitchy tunnel swooper Octagon is free on iPad and iPhone for the 1st time
Octa-price-gone
Octagon is a twisty, twitchy tunnel-based arcade dodge-'em-up in which you navigate through a collapsing eight-sided tunnel of platforms and obstacles.
Good news: it's free on the App Store for the first time right now.
The game looks like a mixture of Boson X and Super Hexagon, and features a migraine-inducing combination of music and visuals.
Given it's free, though, you don't have to worry about selling some of your mum's jewellery to the pawnbrokers down the street just so you can get your greasy mitts on it.
It's always good when you don't have to do that.
