| AI judgment deepseek-flash | Partial AI · solid production, medium confidenceReasoningThe disclosure lists AI use for backgrounds, music, avatars, and translations, which are visible assets but not the core game systems. The developer released only one game in the past year, so there's no volume-release pattern. Four reviews after 17 months is thin, but that alone doesn't establish mass production. Against: AI covers several asset types (art, audio, translation), and the game has very few reviews long after release, which could hint at low effort. |
