Monochroma (PC) CD key

You will find yourself in an alternate past in the fifties in the role of a boy and his brother who are threatened by a criminal corporation. The game starts in a field, from which you take a look at the city and factories, and eventually you head to heaven. Siblings must help one another, for example the older one will carry the younger brother, but when solving problems he has put him in a lit place, because he is afraid of darkness. The game involves realistic puzzle elements, based on the physics and environments.
