A truly great, well polished game with a surprising sense of humour.
The wonder of EDGE comes from its dynamic, cubic levels. Each level is made up of a number of greyscale cubes which create the mazes you navigate. These are populated by moving platforms, pressure triggers, perspective puzzles and much more not worth spoiling. It all looks fantastic too, with fluid animations, clever use of color and an overall clean feel. The audio is great too, with a varied plinky-plonky soundtrack and some very satisfying in game effects, not least the end level crechendo.
With levels floating in an abyss, death comes in the form of moving your cube off an edge, though you reappear immediately at the nearest checkpoint. These checkpoints are invisible, put feel fairly distributed for the most part. Levels in EDGE have no countdown timers, death limits or 'baddies' which gives you the time to experiment and enjoy each stage at your own pace. Some of the more skill maneuvers can be mildly frustrating to learn at first, but you'll be surprised at how quickly they become second nature.
You'll spent at least 3 hours with EDGE before completing the main mode and then still have further missions to unlock by gathering extra prisms you failed to collect first time around. Considering the rocky road it took to arrive on App Store, you should thank your lucky stars you have the opperunity to buy it, and at a measly £2.99 you'd be foolish not to. EDGE is by far one of the best games on the iPhone and among the most enjoyable gaming experiences you'll have this year.
