Edge is played on an isometric field of Gouraud-shaded cubes that the iPhone is more than capable of rendering. Without any textures to worry about, the game has a very clean throwback look to the early days of 3D PC gaming, and performs smoothly. Similar to Super Monkey Ball, Edge strands your cube on a floating playing field in space and presents you an overhead map to assist you in getting your bearings. You begin at the starting point of the field and you must navigate to the exit. Along the way, there are numerous traps to avoid.
