Recently I re-played the 2 episodes (and yet again the game surprised me with new opportunities) and noticed another hint right at the start of the game. Emily says you have already met in London four years ago in the prime minister's office, but Louis doesn't recall it at all. When you meet Sarah in the dungeon, she asks, who you are. From the start of the game there were many Amber series easter eggs, and I think, that there is at least one copy of the protagonist somewhere. Maybe Hillsborough twins aren't even sisters, but copies from different Amber reflections. Maybe the servants wear masks, because they all look alike and it's actually the same person.
The EP2 is quite different from the pilot episode. It's still good and interesting. I love the way you educate players and reward real-life erudition. This episode was more about puzzles and investigation, but lacked the game's unique features. Please add more confrontations and opportunities in the next episodes. This episode indeed had less quests than the 1st one, but it still takes same circa 3 hours to complete, even during a replay, when you already have solved the puzzles. I would like to have more acts in the future for leveling up purposes.
In short, keep the good work up! The only real downside is necessity to wait for the next episode for another 2 months.
