I completely understand the sentiment people have against AI-generated images in games - I work in a field which might soon be obsolete because of AI.
On the other hand I would never have been able to make this game without the recent generative AI revolution. This is a hobby project and while I would love to be able to pay an artist to create the art, the game has not generated the income to pay someone to draw even a single image.
I am not a big company trying to cut costs and I think that in some aspects actually the generative AI could act as an enabler of people's creativity. I'd like to think that this project is one such case. However, you are certainly entitled to your opinion on this matter.
