| Steam disclosure | AI content disclosed |
| AI judgment deepseek-flash | Partial AI · solid production, medium confidenceReasoningThe disclosure states AI generated code and music, with music used as an auxiliary tool for backgrounds, so some shipped audio is AI-made. The developer has only one game and no rapid release pattern, and the game is not yet released, so there is no sign of low-effort volume. Pixel art and narrative tags suggest substantial human work remains. Against: The game is unreleased with no reviews, so the actual proportion of AI-generated music and code cannot be verified. |
