| Source | Their take |
|---|---|
| Steam disclosure | AI content disclosed |
| AI judgment deepseek-flash | Partial AI · solid production, medium confidenceReasoningThe disclosure states some artwork, such as character portraits, was AI-generated, so AI ships to players but covers only part of the assets. The developer has a long Steam history and released no games in the past year, with a modest but positive review base. No signs of mass-produced volume. Against: Only 1 of the developer's 5 games discloses AI, and the game has 37 mostly positive reviews, suggesting a normal single release rather than volume output. |
