| AI judgment deepseek-flash | Minor AI · solid production, medium confidenceReasoningThe disclosure covers only code assistance, not player-facing assets like art, audio, or writing. The developer released one game in the past year, so there is no volume-release pattern. No reviews yet, but the AI use is limited and reviewed, so effort risk stays low. Against: Zero reviews shortly after release and a single release could suggest limited scope, but nothing indicates mass production or heavy AI content. |
