Earlier this afternoon, Eli and I spent some time with Polara ($2.99). It’s an auto-runner with a welcome twist: color-shifting. While doing the standard platform shenanigans, you’ll also be tasked with shifting the colors of the game’s portagonist’s suit back and forth from red to blue depending on the obstacles you stumble across. It’s a cool mechanic in practice, as it adds a superb brain-twistery layer to the action.

Polara is a hit with our readers, and we’re digging it, too. If you’d like to see it in motion before diving in, go ahead — we’ve got your back. Just hit the play button on this thing below.

For a limited time, the game is on sale for 99¢, by the way.
