A green ball named Williams explores strange rooms for interesting things. On the way, he finds ingredients that make him stronger and make him grow. And he has different ways of transformation and can transform into any form without exception. The only thing that he lacks is intellect, which can not contribute in full in those locations where it is really necessary to think through each step. Start together with the character on a trip and try to pass together one room after another. Turn the mechanisms of closed doors with stone boulders.
