In the interest of reporting bugs, I noticed this line seems to be hardcoded to use "Orion" instead of the player chosen MC name:
Also, for some reason when I replayed the update to see all the Hyril'ar content (my main save is on none of the paths, mostly on account of stubbornness at this point), it somehow unlocked not only "Royal Proxy" in the gallery, but also "Knotty List" and "Third Degree" even though I hadn't triggered either of those scenes. It notably did not unlock "Paranormal Activity," though. I suppose I might have inadvertently broken something by poking around with URM on my first playthrough, but I don't think that should be the case, and I definitely hadn't unlocked any of the new scenes in my initial run.
As for the update itself, pretty good. Luna is awesome as usual and the Christmas bits were fun. The
civil war plotline does feel rather extraneous when it's introduced this late in the game, but presumably it will figure into the finale somehow so I'll withhold judgement for now. Fortunately, the characterization for Calypso was fantastic; it's a shame we need to be obsessed with getting into her pants to see any of her development, but I suppose that's just how harem games roll.
Never tried it,but think you'll need renpy sdk,then you unpack Eternum with unren,open it with renpy sdk,and then, there is an option "generate translations" that creates translation files you need to manually translate,and then you can share it(Not sure about switching the language inside of the game without touching preferences screen)
