an explicit statement that no teleporters require a receiver. That was the justification for the prototypes I believe; something along the lines of the "receivers" not technically being necessary and only there to provide a route back, which is what gave them the inspiration for the variable teleporters. So the idea was supposed to be that the first models did need receivers, but you lost that in the shuffle somewhere?

And you still didn't explain how the Nexus crystal got misaligned after Gram used it. :p Maybe he collapsed into it or something, so he teleported successfully but misaligned it in the process?

That's an interesting detail about the crystals being born of meta-necessity. I've heard a lot about game devs having to come up with creative workarounds for technical limitations, so it's neat to see that. I do feel you use it a bit too liberally, though; any time the plot needs some magic you just shout "saecelium fallout!" to hand-wave it. What particularly threw me was Darius being all "oh obviously saecelium can turn people into ghosts, you know that" when...no??? All we see is that it locks people into a time loop; turning people into ghosts doesn't seem to fit. Maybe if it just made him ageless and not literally an intangible spirit, but it seems like that should freeze him in time to be consistent with the Flying Mountain people. Plus Oliver saying time travel is impossible only to be immediately contradicted in Raccoon's soul tear where Solomon says "oh yeah I totally just time traveled, NBD", but I presume that one will be addressed.

Would you still have had magic spacetime-warping technology even if you went with regular computers and stuff?

So after all that exposition about how Ubiquity can't be reached with normal teleporters, the Sanctuary teleporter can do it just fine? :p While I appreciate it from a gameplay perspective, it does seem a little silly. Might have made more sense for it to only go to the top of the space elevator.

where's Mint's Ribbon, or is that permanently missable?

I felt the ending was really unsatisfying, in general. There are a lot of plot threads that I thought would be answered but just got dropped. How did Raccoon discover the location of the space elevator, for starters? That's something that Oliver expressed confusion about but it's never explained. Even if we're to assume he read the central research database (which he must have, but how did he get in there?), it doesn't say where the space elevator is. Solomon's Flying Mountain crystals don't have that information either. So how did he find it? I recall Oliver saying it was odd he knew how to operate the Flying Mountain, too, and the central research database doesn't have the information he would need for that.

Then there's the fact that the populace appears to worship Christianity (crosses, churches, Mass on Sundays) despite this apparently being a fantasy world with no connection to Earth. When the little girl in Balfur asked "What does this mean?" my immediate reaction was "That's a very good question, I hope we get an answer!" I kept expecting a big reveal that this was the future of our world and the Lydians were genetically modified supermen or something, but then...nothing. I presume this was another limitation of the RTP graphics, but in that case why did you include the "Mass is on Sunday" line? And how do they know what Halloween is??? o_O

And related to that, I was really confused by the tech level. At first it appears to be standard medieval fantasyland -- swords, shields, monarchies, magic -- but once we get to Silver Spring it becomes clear that the world is swimming in modern cultural and technological elements, including guns. How on Earth does medieval equipment coexist with rifles? Is the idea supposed to be that gunpowder was a very recent invention and these are supposed to be, like, 1500s-era rifles that are really unreliable? Except they have EMP generators too, which seems pretty advanced and begs the question of why they don't seem to have electricity. I presume this is another RTP limitation but it makes things really, really confusing. Even limited to the context of saecelium technology, I was confused -- I thought people didn't know about it because it was never mentioned prior to the Flying Mountain, but post-timeskip everyone's talking about it like it's no big deal. I suppose that could be explained by people learning about it after the Flying Mountain incident, but it's still not very clear.

Also... I poked fun at this in "Ask Mint", but the girls are very worldly for kids supposedly raised in isolation. Seriously, how does Ivy know what a vegetarian is? She's never heard the term. How does Mint know what dogs are? Unless Gram had a picture book of animals, she's never seen one. How does Ivy know about taxes, governance, and changing public policy (which she does, judging by her reaction to the teddy bear sidequest in Silver Spring)? There is some wiggle room in that Gram must have taught them some things, but he must have given them a very elaborate education to cover all these things that he never intended for them to have to deal with in the first place. Basically, they act like people from our world transplanted to a fantastic setting, not isolated people being exposed to the world for the first time. The girls (well, Mint) do react with awe and confusion to the fantastic elements, but not to mundane things that should be equally new. There's a lot of potential in characters like Mint and Ivy, so I was disappointed the story went with the easy route of just making them audience surrogates.

Finally... I'm pretty baffled how you expect players to have any sympathy for Raccoon after revealing that his motives were 100% purely selfish. When I saw the soul tear I thought that he had gone to Ubiquity to confront Solomon, and that there was going to be some epic showdown between the two well-intentioned extremists that would end with blowing up Ubiquity to mercy kill them or something. But he just did it because he wanted to be immortal? I don't want to save someone who worked hundreds of people to death for his own self-interest, especially when going about it in such an inhumane manner was completely unnecessary. Why does he even want to prolong his life in the first place when he's suicidally depressed and places no value on his own life? Did he think that ascending to godhood would make him feel better?

It's also not clear how Raccoon changed so much in the first place. I presume you wanted it to be ambiguous, but he still shows such an extreme change in personality, even one year afterwards (according to Gaul's soul tear). How did he go from vowing to protect Yvette to such extreme nihilism? I expected Solomon's crystals to have been some really freaky, world-shattering stuff, but "your ancestors were from the distant past" is really, really tame; moreso than people trapped in endless loops, I would say. I find it hard to believe that that alone would be enough to warp his mind. Is the idea supposed to be that he was thrown by Mint's death even more than Ivy was? That's not very clear, given that he interacted with Yvette a lot more.
