Monument Valle is a visual and auditory feast, fresh images with ethereal music, pull yourself into that mysterious map, into which you can not extricate yourself. The background music flows slowly, without a high note, low and heavy tune is like the soul singing, but also like the deceased in pouring out some injustice.
