| Steam disclosure | AI content disclosed |
| AI judgment deepseek-flash | Partial AI · solid production, high confidenceReasoningThe disclosure states AI contributed to background art and served as reference for CG and character elements, so some shipped assets are AI-influenced. The developer has released only two games, one disclosing AI, with no high-volume release pattern. 45 reviews at 66% positive indicate a real, reviewed release rather than mass-produced volume. Against: AI use appears limited to backgrounds and reference work, with most art and design likely human-made; the developer's release cadence is low. |
