I see, thank you for letting me know! Awesome to know the story is intended to continue and looking forward to it one day!
btw if you liked the atmosphere of this and don't mind gore, there's an old manga called 'BLAME!' that's pretty similar. There's also an animated film adaptation on Netflix that's not bad.
(It wasn't an inspiration, I learned about it later, but I just thought you might enjoy it.) Warning, BLAME! is not just gory, it's also fairly grim. Crust will be a little more optimistic, I think.
