There's a lot of things going wrong here.
Yes it's AI art. Not much more to say there. The various characters all look the same and made of cheap plastic like most other free AI models out there. I think the bodies are all identical with a few slightly different heads. I get not everyone can afford an artist, but at least make an attempt to generate different looking designs.
The main 'gameplay' is breeding rituals, but it's an insanely clicky chore and a pain (as in literal pain if you play for more than an hour, that's how clicky the UI is). 99% of the time you get trash joke items, and then once in a while you'll get a new slave. It takes forever to get going because of this, as your gold income is entirely based on completing slave turn-in missions. Also for some reason the rituals instantly create new slaves, but the 'story' characters you can impregnate have to go through a full pregnancy cycle.
There's a rough concept of a colony sim, but that's all I can say about that. Population doesn't do anything and just seems to be a net negative (more food required). Stones and ores appear to have zero use at the moment. There's a...calling it tower defence is being too generous...mini-game where you have to defend your colony every so often. But you can't do anything more with it other than build a bunch of basic towers and occasionally push one of the special ability buttons. The enemies are also just skull icons at the moment, and don't do anything more than hover forward at different speeds.
In its current form, this a 1 star game but the dev does seem to be trying with regular updates so maybe in a year or two there will be a more interesting game. For now I can't recommend this, and 2 stars is the best I can give this.
