I like the honesty, and I get the intention. Certainly I'm not exactly good at abstract art, so I can see why using AI for that could save some headaches trying to come up with something useful. Specially when the concept is literally eldritch alien, but not the usual spirals and tentacle monster stuff (I'm really glad you chose to not go this route, that would make the game just another one on the pile)
The results are uncanny and quite unique, and tbh the reason being "AI sucks so it fits" is honestly hilarious lol.
