| AI judgment deepseek-flash | Minor AI · solid production, medium confidenceReasoningThe disclosure limits AI to certain images on the store page and in the prologue, with gameplay unaffected. That is a small, supporting portion of what ships. The developer has a multi-year Steam history and only 3 releases in 12 months, so no volume-release pattern. Against: Only 19 reviews at 68% positive 15 months after release, and only 2 of 12 games disclose AI, so disclosure habits are inconsistent. |
