I finally gave this one a try and I have to say, I'm seriously surprised by how creative the whole concept is, and beyond that just how good it is. The writing and the art fit together perfectly from conception to execution. That might be in part because (educated guess on my part) that the realities of using AI image generation means that the writing and the art both inform each other rather than the usual art derived from writing method. But together it just... works.
And I don't mean in a gameplay sense. Just as an example, the idea of using malformed images for enemies - and giving them a well-written in-universe reason to be so - is such an interesting way of avoiding the pitfalls of image generation. This, among other things, gives it that dream-like quality that I have always adored about this kind of shifting-reality fantasy. What could have been detrimental instead ends up being part of the charm, and there are quite a few little details like this.
A little bit of a rant here (bear with me), but story-wise it relies on a host of tropes that I have always found to be trite at best when it comes to this kind of game. The whole being sent to another world shtick, being the only (or mostly, anyway) man in the world, especially the magical reproduction, et cetera. To me these are synonymous with writing somewhere around the level of bathroom graffiti even individually, let alone all together.
But all these cliches that I normally avoid like the plague are somehow endearing here. It's like you saw all the same problems I did, but instead of hating these ideas you instead decided to redeem them. And I am glad you did, because they it seems they actually had real value, but more than that they clearly deserved far better than their usual treatment!
Anyway, I mention this specifically because I hate all those tropes, and yet I love what you've managed to do with them. And if someone who doesn't even like half of the basic premise (though admittedly I am a sucker for this particular brand of fantasy world) still can't help but admit that the end result is good, then you've obviously made something special.
