Well, one thing i said to the faithful was why if CIG already have Pyro (and some cases they claim other systems as well), why don't they just have separate servers which you can select from on start to play in different systems? To which they tend to respond with some waffle.
But yes, in this case we are talking about the stage where CIG actually have a second system in game that is reachable via wormholes.
Maybe you don't remember, but CIG first showed off the loading screen... sorry, jump animation many many years ago. I think circa 2016. And they showed it off again somewhere around 2020. They love to tease backers that Pyro is coming (then rugpulling it some time after the next citizen con).
By the way, its meant to be a bit of a minigame, where you steer your ship through the wormhole. As i recall, when they first showed it off, during a presentation, whoever was presenting it, i guess Chris, said something like "You need to be careful not to touch the sides of the wormhole, because that's bad for the ship". Seconds later, the person flying the ship touched the side of the wormhole and nothing happened to the ship

Probably Tier 0 alpha!
I'm sure backers will say its not a loading screen and that you're actually flying through space, and it can't be a loading screen if you are doing something. I mean, some might remember the Mass Effect elevator loading screens, but even as far back as the days of the ZX Spectrum there was at least one game where you could play a mini game while the game was loading. Wish i could remember what that game was.
