As has already been said, this game has a really great sense of humor, leaving me laughing at many key moments (such as when the crew fix the spaceship with percussive maintenance). The characterizations of the main cast are great too, feeling quite real. Ofc it also runs on porn logic but that's to be expected.
One thing that stands out to me is that the main character isn't just a blank face for the audience to project themselves onto. I really like his unique design with the facemask and corny clothing. And he has a bit of a personality, mediated through the constant choices to be kind, funny, or dickish. Too many VN-type games have the problem of the male MC being bland.
The addition of a guide on the steam version is also great, even if the plot of this game is pretty railroaded (not that that's a bad thing), but it's not quite integrated within the game like in Being A Dik - it just opens a PDF.
Is there anything that needs improvement? Well, as of writing, my main complaint is that the story isn't complete. Apart from that, maybe the VA for the MC isn't quite the right fit, but that's being nitpicky. Sex scenes could be a little longer (more dialogue), but that's just my personal preference.
Overall, easy 5/5, definitely the most fun VN I've ever played.
