In many respects, ngmoco’s platforming puzzler Rolando was the iPhone title that validated Apple’s mobile as a viable gaming platform.

Inspired to some extent - certainly aesthetically - by LocoRoco on PSP, Rolando rolled onto iPhone in December 2008, complete with jaunty music supplied by Brit DJ Mr Scruff.

Whether seduced by Mikko Walamies’s artwork, THAT infuriatingly catchy soundtrack, or the simple swipe-y control mechanism, players weren’t likely to forget the inhabitants of Rolandoland very quickly once installed.

Well, the original and its 2.5D-favouring successor Rolando 2: Quest for the Golden Orchid are now on sale for 59p, so grab 'em while they're cheap.

Even better, the pair have been updated with optimised graphics for Retina displays, which is only about nine months in the waiting. Heigh-ho.

Anyway, check out our reviews of Rolando and Rolando 2: Quest for the Golden Orchid. It’s definitely worth it, since they both received top marks from AppSpy.
