As others have said, most of the negative is semantical.
It keeps saying they're green, when they're pretty clearly yellow.
It frequently calls them orcas which, while funny, certainly doesn't seem intentional.
When referring to one of the girls, it always says "him/his/he".
Some entire lines aren't even translated, so sometimes I had no clue what they were saying because I couldn't be bothered to pull up a translator myself just for one line.
Things like that, which are all obviously attributed to translation errors, so not really all that big of a deal.
Also, one option with the phone girl (I don't remember her name) makes the MC behave uncharacteristically...evil? Sadistic? I'm not entirely sure what to call it. So that was also odd.
I'm glad to say though that most of those qualms are only nit-picks. I don't have any major issues with the game otherwise.
The art is so-so. Not bad, but I wouldn't particularly call it good either. "Average", I guess. The character designs are great, however pretty much anything NSFW looks weirdly...I don't even know how to put it, I guess "over-detailed? It doesn't look like the rest of the art, but only by a little bit. But it's enough to look a little out of place.
Otherwise though, I like the style. I like the girls' design. The story is actually cohesive. There just isn't all that much content yet, but I can't fault them for that, since that's practically the norm on this site.
I look forward to seeing some more development and polish!
