Polarity takes place across a series of small rooms where everything of note is either blue or red. Or neither, I guess, but you'll always want to focus on the colorful things.Color is key,as that's how you know what will happen when you interact with certain obstacles. Shimmering blue platform hovering over a pit? Switch your polarity to red and you won't pass through. You'll also pick up polarized cubes and use them to activate platforms, doors, jump plates and more, all in the name of hacking.
