The construction, concept, format, style, and overall design are fantastic and possibly go even further than that, much more so than how it had started beforehand!
Not only that, but they also show much more attention to detail and an improvement next to how it looked previously from a while ago compared to how your first/previous/last visual novel that is known as "Adastra" had begun and then got finished up some time ago after you first uploaded/posted this VN afterward!
That's not to say that the previous artwork or character designs were necessarily bad either (in between both of those visual novels a.k.a. https://echoproject.itch.io/adastra, https://echoproject.itch.io/khemia); they were all still great, whether set on another planet, a spaceship, or anywhere else, but it seems like there was more work, energy, emotion, and several other things put into this that make it 10 to 100 times or even more so better than before as compared to the last version of "Khemia".
With that said and done, though, I’m just glad to see that the novel will start receiving new chapters and updates again. It’s exciting that it will continue from your other visual novel, Adastra. I was becoming worried that it might remain on a permanent hiatus, leaving the story unfinished forever and keeping us in the unknown about what will happen next for the rest of our lifespans leading up to us now never finding out what will happen to the characters until at the end of our life and perhaps even until the end of time as well (!).
