  • What is the purpose of the 'rules' specified in the prompt template?

    -The 'rules' in the prompt template guide the AI on how to generate the game's narrative. They define the structure of the game, including the types of choices to be offered, how to handle success and failure scenarios, and how to end the game.

  • How can the game's difficulty or complexity be adjusted?

    -The game's difficulty or complexity can be adjusted by modifying the rules and structure defined in the prompt template. For example, by adding more paths, decisions, or specific conditions that must be met before reaching certain game outcomes.

  • What is the benefit of using the LangChain library in this project?

    -The LangChain library simplifies the interaction with the AI model and the database. It provides an easy-to-use API for setting up pipelines, handling models like language models, and managing memory, making the development process more efficient.
