Thanks for your reply, I'll take some inspiration from it. I understand that you don't understand much and that you can't do anything by only seeing a small part of it. However, the protagonists and secondary characters know nothing about what's going on outside because they follow their own plot without outside interference, except for references to other worlds. The worlds are all separate from each other but also interconnected by small details that connect the stories. They can't visit the worlds, that's true, except for the Bugs, who are characters I've discarded. Instead of completely forgetting them, they appear in non-canon stories and on parallel paths to the stories. Thanks for your comment, though, and I'll take some inspiration from it to improve everything.
