| AI judgment deepseek-flash | Partial AI · solid production, medium confidenceReasoningThe store disclosure states AI was used for some images and music, so AI content ships to players. That covers only some asset types, with no sign of mass-produced volume: the studio has one game and no recent releases. Not yet released, so effort signals are limited. Against: The game is unreleased and the studio has no release cadence, so there is no evidence of low-effort volume; AI use appears limited to supporting assets. |
