Cubicus Arcanum

A mysterious voice calls your help from an interdimensional portal. Persuaded (but you don't know well why), you accept the request to jump inside the scary portal in front of your eyes. The travel makes you unconscious. When you wake up, you find yourself in Cubicus, a world made of cubes and, in front of you, a scientist-looking cubeman is talking by himself about his own discoveries. When you ask him to explain better the story, he just hurries you up to find the blue gems telling that there's no time to waste. What happened to Cubicus? Will you be able to know the secrets of this arcane world?
