I finished the DLC and can only confirm what you say. Superb finale. Thats how a swapping game should end. Awesome scenes with satisfying dialoges.
It is a shame that this wasnt in the main game and we had to wait for 4 years!!! And there is even a second DLC we still dont have (i think it is about Yukaris past).
How did you hook the game? When I used ITHVNR, only certain lines got translated for certain hooks (Like one hook translated the MC's inner thoughts, the other hook translated the dialogue of one character, another hook translated the dialogue of another character, etc.). Its technically playable but Whenever a different character speaks or the MC's inner dialogue pops up, I need to switch hooks to be able to acquire the text to translate. I'm running into the same problem with Textractor as well.
