Tiny Screen Adventures: Monument Valley

Monument Valley is an elegant little puzzle game for IOS.  You guide The Silent Princess through a world of bridges and towers and rotating platforms.

Sometimes she’s upside down or sideways but she can always make her way along with a twist here or there.
There is a storyline but I’m only up to chapter five so I can’t guess what our mysterious Princess is making her way towards.
Music in the game perfectly fits the gameplay.

Note:  I’m stuck on level 5 😦     The crows have me blocked and I am not seeing how to bypass them.  I will give it some more effort before I cheat and see if anyone has tips.
