Reasoning

The disclosure states AI was used for some character portraits, a visible in-game asset, so scope is parts. Story and dialogue are human-written, and the developer has a small catalog with no rapid-release pattern. Translation and store-page AI use is minor.

Against: Only 1 of the developer's 3 games discloses AI, and the game is unreleased with no reviews to gauge effort.
