On a sunny Sunday morning, Mr. Ooyai went for a walk, his traditional exercise, which he had not violated for many years. However, today everything will change and you will witness this in the game Mr. Ooyay's Mystery Walk. So, the hero followed his usual route from the house to the park and further along its paths. Suddenly, a circle appeared right in front of him, within which something flickered and shimmered. Unable to resist curiosity, the hero stepped right into the circle and found himself in a completely different world, where he himself changed, taking the form of some kind of square two-dimensional character. At first, the hero was frightened, but then he saw the same portal nearby and thought that he could return in this way. The poor fellow does not know that he will have to go through dozens of such portals before he returns home. Help him in Mr. Ooyay's Mystery Walk.
