What parents need to know
Parents need to know that Edge is a physics-based puzzle platformer game involving a simple mechanic: Move your cube from the beginning to the end of the level by rolling it in different directions and adapting to challenges like conveyor belts, uneven terrain, and moving platforms. There's no objectionable content to watch out for, but the game does require the kind of fine motor control and critical thinking skills of a child of perhaps 8 to 10 or older.
Is it any good?
Gameplay with EDGE is somewhat similar to Super Monkey Ball 2 except that instead of tilting the environment, you control the direction of the cube itself. Levels become increasingly challenging, but the learning curve is manageable and the game is forgiving of mistakes. There's often more than one way to finish a level, too, so players can go back and try to beat their time by trying different strategies. Edge isn't a flashy game, but its graphics and gameplay are elegant in their simplicity and perfectly suited for the iPhone or iPod Touch.
