The good news: Mobigame's popular iPhone and iPad puzzler Edge has been updated with 16 new isometric levels. The bad news: unfortunately, if you want to play them you'll have to splash out 69p/99c on an in-app purchase.

The aim of the game is to navigate a small cube around several floating mazes, collect even smaller cubes, make full use of multiple platforms, and reach the end of each stage without falling to your demise.

We gave Edge an impressive Pocket Gamer Gold Award when we reviewed it back in 2009. You can grab it for £1.99/£2.99 on iPhone or iPad.
