The final step to balance mechanics to create mystery is to adjust the difficulty and feedback of your game. This means setting the level of challenge and the amount of guidance that your game provides to the players. The difficulty and feedback can affect how the players perceive and respond to the mystery, and how satisfied they feel when they solve it. For example, if you want to create a game with a high difficulty and low feedback, you might use mechanics such as permadeath, randomization, or ambiguity. These mechanics can make the game more unpredictable, risky, or open-ended, and force the players to rely on their own skills, intuition, or interpretation. However, this can also frustrate or confuse some players, and make them lose interest or give up. On the other hand, if you want to create a game with a low difficulty and high feedback, you might use mechanics such as hints, checkpoints, or tutorials. These mechanics can make the game more accessible, forgiving, or instructive, and help the players to overcome obstacles, learn the rules, or follow the story. However, this can also reduce the challenge or the mystery, and make the game too easy or predictable.
