Echochrome launched on the PlayStation 3 and PSP a little more than a year ago, and it broke my brain. The game looked simple -- there was no color and you were a feature-less mannequin -- but it was this brain cell-burning puzzle that had you getting your one dude from Point A to Point B by rotating the world, using black holes, and basically living in an M.C. Escher drawing. It was a scene, man.
Now, Echochrono is exclusively storming the PSP from ARToon.
