I asked on Discord about what else I should have Fam play and bobbens told me that she could cover the other missions. A great idea since the lack of guides is the exact reason why I’m making them, the puzzles got so hard that I wanteed a guide.
At this point I’ve played much and can say that I likely found the end of space which has to do with the hidden things behind Sol. I couldn’t find much in terms of miaaions for it in the files but they’re right there, behind the Sol system.
I’ve done some more missions and none of them get you through Sol either so I guess it’ll remain a mistery.
