World of One — is a gloomy and very depressing platformer on PC, which takes place on several small circular planets. The protagonist wanders through these worlds in a free mode, but he is guided by pressing questions about his purpose, about the benefits that he brings or does not bring, and why he is here. Only the most inquisitive and insatiable mind for puzzles can find answers to them. The gameplay of World of One is based on physics and interaction with interactive objects.
