Back in November, the superb auto-running platformer Chameleon Run randomly went free on the App Store. While that was a very short-lived giveaway due to an accidental flip of the sale switch, this time it’s for real: Chameleon Run is currently free to download on iOS. Although today’s markdown also snuck in under the radar, one half of the two-man development team that is Hyperbolic Magnetism acknowledged the sale on Twitter, citing it as a nice method of cross-promotion for publisher Noodlecake.

If you haven’t had a chance to try Chameleon Run yet, we absolutely recommend it. It’s a level-based platformer that uses the seemingly simple controls of jumping and changing your character’s color to match the platform’s he’s traversing in order to create high-speed, exhilarating races against your own best time. Each stage is very short, but packed with tight platforming challenges and bonus objectives that make replaying levels both rewarding and interesting. At the time of launch, our only complaint was that we simply wanted more levels because we couldn’t get enough. Since then, the game has been updated with an additional world with four more levels and new achievements, so our appreciation has only grown.

In fact, we almost hesitate to announce this sale since Chameleon Run is already a steal at its usual price of $1.99, but we love a good deal. And this, like the game itself, is a great one. Head over to the App Store to snag one of our Top 10 games of 2016 for nothing—except the time you’ll inevitably lose to its addictive, just-one-more-level grasp.
