All challenges awaiting the player are thoroughly described in the guide, some of them referring to screenshots found above the text. In such cases, it is clearly stated. Names of all the objects found in the game have been marked with blue.
Throughout the game you can control three characters and switch between them at any moment. The cave which you will be exploring has an open structure and some challenges will appear regardless of what characters you choose. Some, on the other hand, are connected directly to given characters (one to each of them) and will be unlocked only if you meet the requirement of having them in your team. Therefore, in order to learn the story of all the characters in the game, you will have to finish it at least twice and start a third playthrough to a certain moment.
Guide shows how you can solve all the puzzles in the game. It's divided into chapters corresponding with particular sections of the cave which you have to go through during each game and into chapters connected with given characters.
