What the developer wrote

The audio in the game is not produced by machine learning models. The game images are divided into two categories: ① The vast majority are generated programmatically and not by machine learning models; ② The character illustrations are generated by machine learning and then selected, cropped, and post-processed by humans. The game text (environmental narration, entry descriptions, achievement descriptions) is drafted by AI with assistance and then revised by humans before being included; developers conduct fact and expression reviews of all game images and text before release. The game does not have an AI system for real-time generation of content, and player input will not be used for training or content generation.
