You might remember echochrome from the last time we typed about this hugely promising puzzler. It's one of our most anticipated titles on PSP this year. Really, it's potentially that good.

On screen, a game about a "mysterious wandering mannequin through a brain-teasing array of 3D mazes full of hazards and perils" may not sound like much. But the beauty of echochrome is that you overcome challenges by changing the viewpoint and perspective of the mazes – if you've played Crush, you'll already be a step ahead of the rest.

Anyway, the point of this update is the fact that the European release date appears to have been set as May. So says the game's page on Sony's PlayStation website (as spotted by eagle-eyed PG reader HiddenAway).

The site also divulges a little more info about the game, including the 'five laws of visual perspective' that govern its gameplay and give you more insight into the experience that awaits you.

What are they?

Well, the Law of Perspective Travelling states that when two separate pathways appear to be touching, they actually are.

The Law of Perspective Landing relates to the fact that if one pathway appears to be above another, it is.

The Law of Perspective Existence, meanwhile, dictates that when two pathways appear connected and the gap between them is blocked from view, they are.

The fourth law, of Absence, extends the above concept so that when a gap is blocked from view, it doesn't exist.

And, finally, the Law of Perspective Jumping sees the mannequin landing on anything that appears to be beneath him after a jump.

Got all that? Good. All that's left to say, then, is the fact that you can create your own mazes and share them with friends or fiends via ad-hoc.

That's it for now. Let's hope the game sticks to its May release because we're not the most patient people you'll ever meet. And we want to get some decent time with this game. In addition to the demo already released, that is.
