Ustwo's gorgeous, mind-bending puzzle game Monument Valley just received a massive new update that almost doubles the length of the game, with the addition of eight extra levels.

These bonus stages feature entirely new concepts like water, upside down sections, spiralling walkways, and gusts of wind. So you might need a helping hand working through them.

As ever, this guide is intended for those who get really stuck. We recommend you stick with it and try to figure it out on your own to get maximum satisfaction from the game. But if you just can't do it, read (and watch) on.
