The developer has a small catalog (2 games, 1 in the last year) and the game has 8 reviews at 87% positive, showing no volume-release pattern. No other AI use is indicated. Against: Both of the developer's games disclose AI, but the disclosed use is limited to translation and the developer states the output was reviewed. |
