| AI judgment deepseek-flash | Partial AI · solid production, medium confidenceReasoningThe disclosure states AI helped create certain art assets, proofread text, and check code, so some shipped assets are AI-generated. The developer has only one game and no rapid release pattern, and the disclosure describes human review and finalization. This points to limited AI use within a human-led project. Against: The game is unreleased with no reviews, so the actual extent of AI-generated art cannot be verified; the disclosure is vague about how much art was affected. |
