¿Cómo jugar Ilumicatis?

About ILUMICATIS, from BoardGameGeek:

Four adventurous cats must traverse the three realms-Hell, Purgatory, and Paradise-to reach enlightenment and achieve victory. Although they must cooperate to overcome each realm's challenges, all of them can win together if they reach the portal to Paradise before Gatoraculo gains enough points by defeating them. This is a semi-cooperative game: the cats must work as a team to solve puzzles, win battles, and advance from one realm to the next, but they are constantly threatened by Gatoraculo, who will claim victory if they fail. Luck and their seven lives won't be enough; they must be strategic, collaborative, and wise in choosing which decisions to make and which enemies to confront.
