| AI judgment deepseek-flash | Minor AI · solid production, medium confidenceReasoningThe disclosure limits AI to a single menu background, a small cosmetic element. The developer has released only one game, so there is no pattern of volume releases. One review long after release is thin evidence but not a mass-production signal. Against: The game relies on pre-made assets rather than original art, and has only one review 20 months after release, which limits how much effort can be confirmed. |
