Puzzles involve trading these or using these items to receive new items or to get past obstacles, allowing the player to progress. The game in general honors non-violent solutions, offering more points for them. Many puzzles have more than one solution, but only one optimum solution to earn maximum points. Alternate solutions will net less points or in some cases cause the player to lose points. Examples of alternate solutions are taking more violent approach to getting past an obstacle such as killing or stealing. Some choices may lead to dead ends or death.
