1. Asset Creation: Generative AI was used to create base images for some backgrounds and non-character card illustrations (such as items or objects). All these assets have been manually edited and processed by the developer to fit the game's art style and ensure they are used appropriately. 2. Translation: AI is used, as the translation is primarily based on machine translation. 3. Real-time Generation: The game features an optional AI text generation system for exploration flavor text. This function is only activated if the player provides their own API endpoint. The generated text is based on in-game variables (player skills, partners, and floor names) and does not affect the core story or progression. It is a purely cosmetic addition for enhanced immersion.
