If we had to pay for the game, I would agree. Seeing as it is a free download, I don't see a problem with downloading and finding out. If the game was paid and he did not admit to the AI imagery, that is another story.
Nobody cares about AI imagery. The developer literally put time into coding the game. Nobody wants to hear a bunch of overgrown kids whine about AI imagery in a game that isn’t even complete yet. Art always takes the back seat with games like this so just stop your whining already.
