I feel much the same way. Seeing these characters again was the best part but otherwise Act 2 is just a massive slog with puzzles that are either nonsensical or drag on for wayyyyy too long. The court segment for example, while cool, really overstayed its welcome, And the final puzzle at the front of the train was actively frustrating for both me and the person I was playing with. There ARE hints but not only are they not always available (and this seemed to be the case for when we always needed them most), but ideally the puzzles should be solvable without needing to resort to that or brute forcing every item on every puzzle. Act 1 also had this issue but to a much less egregious extent since there were way less rooms and items to work with.
