Echochrome was one of the downloadable games from the Playstation Newtork that were demoed for Loot Ninja at Sony's Media Day, and from what they saw it looks to be a very tough, but creative game. The concept is really cool; take a 3-dimensional environment, and using the left and right analog sticks, manipulate your 2-dimensional view of it so that your character can pass through to different checkpoints. How does this work? Lets say for example that there's a gap in the platform you need to walk across. One way to get across would be to turn the environment so that there is another object blocking your view of the gap. The game is all about perspective - it works based on the Object Locative Environment (OLE) coordinate system - which basically means that if you can't see it, then it's not there. If you can't see the gap in the platform, then your character doesn't know its there and will walk straight across. This is just one of several interesting mechanics used in the game. This preview has a few more.
