"If you haven't already downloaded echochrome (it went live during Thursday's Store update), you've got 56 brain-busting, perspective-spinning puzzles ahead of you. If anyone out there has already managed to clear all the levels, these people are looking for you. Still, you've hardly seen all echochrome has to offer. Aside from *another* 56 levels to be found in the other version of echochrome (both the PS3 and PSP editions contain unique level sets), you can also play the best levels your fellow gamers have created."
"Every level has to have 3 things: a start, pathways, and a goal. The mannequin piece acts as the starting point for the level. You can build pathways with as many gaps, obstacles, and bends as you like. The goal is to reach the echoes, or shadow guides. These are like markers that you have to guide the mannequin to. So you'll need at least one of these. You can place up to four echoes anywhere in the environment, while the fifth and final echo will always appear exactly where you place the mannequin character."
