Echochrome has arrived on the Japanese PlayStation Store in PS3 demo form, so if you've got one of those fakey PSN logins, you might want to indulge.
(Update! Having finally gone home and tried it out, there are PS3 and PSP versions available.)
Kotaku reports that the demo is the same one played at TGS, which would mean you get a tutorial on how to play.
The most recent code we've seen, at GDC last month, featured three levels of varying difficulty.
Sony has yet to get back to us about whether the demo will be available to the likes of us today, or at any other date in the nearish future.
Echochrome is a puzzle game where the position of the camera determines physical level conditions. For example, if you rotate the camera so that a vertical beam obscures a gap between a pair of platforms, the game behaves as though the gap no longer exists.
The goal of each level is to rotate the camera so that a little man walking steadily along the beams and platforms - over whom you have no control - moves untroubled between objectives.
It's very odd, and could be very good. Sony has yet to expressly say when it will be released, but we've been told to expect it in Q2 for Europe. As well as PS3, it will be available for PSP.
