Mediocre.
This rating has nothing to do with the AI art, which doesn't have any distracting errors, so I assume some cleanup was done, but also, there just isn't as much art as you might expect. Consider the art a neutral rating. It's pretty, but vapid, much like this game overall.
Unfortunately, there just isn't much here at all. What you see in the previews is all the sex there is in the game. No, I don't mean that those are screencaps from those scenes, I mean that there are about five explicit CGs that comprise half a minute, maybe a full minute, of actual sexual material. You wake up to the captain masturbating... and then go back to sleep. (In four or five runs through, I couldn't trigger a proper scene.) There's a nun with 'uuuuuuuge... tracts of land that takes you to her bedroom... and then you sleep. You do actually bang the chameleon girl, but the scene is barely long enough to unzip your fly.
Clearly, it's not that the developer can't get explicit CGs. But the way the writing makes you feel like you missed out on sex every scene while strongly hinting that there'll be sex "next time" feels like the kind of cocktease MarbleSyrup games used to do. They're even trying to milk this on Patreon just like MarbleSyrup. There is nothing here, just the tease that maybe there will be something worth throwing money at. It's yet another developer holding their hand out before they've actually made anything of value.
I probably would rate this at three stars for what it is, but there's no aspect that stands out enough for me to have any faith that this game will be worthwhile. My recommendation would be to look elsewhere, and especially to keep your money for at least a few more versions.
