Wrap your head around the impossible spaces in gorgeous upcoming iPad puzzler Monument Valley

I was, and still am, jealous of PG editor Mark Brown for getting the chance to play ustwo's Escher-inspired puzzle game Monument Valley.

"Monument Valley is constantly changing the rules, from level to level, in ingenious and totally unexpected ways," Mark wrote.

Monument Valley is not easily described with words, particularly if you're not familiar with the 'impossible' architecture of the aforementioned Dutch graphic artist.

Imagine vertical labyrinths that have staircases leading to nowhere. Platforms that defy any logical understanding of space. Yet all of it is connected, somehow.

Escher managed to pull off this sort of visual trickery by toying with the isometric perspective. This is a technique ustwo has employed to great effect in Monument Valley.

You turn the world on its axis, much like you did in Fez. Upon doing so, paths that would never match up suddenly join. It might take a while for your brain to adjust to all this, by the way.

Anyway, take a look at the four newly published Monument Valley screenshots in our gallery up there on the right to get a better idea of what I'm talking about.

I've been scanning those screens for the past few minutes, trying to figure out how the various paths link up when you turn the world. It's not easy.

Anyways. Monument Valley will be leaving our heads spinning in 2014, providing you've got an iPad to play it on.
