You will have space where the protagonists will be the people of the Ice Age. They brought in deep space, where there was a time curvature and now it is not clear where the future is, and where present. Look at the two identical pictures and try to find ten differences on them for some time. You have only three attempts, if you spend it in vain, it will lose. If you press the right contrast to get points, try to score the maximum number and win.
