Brilliant game. The puzzles are generally harder than those found in many of Emily Short's other games, but are still reasonable. I found a rare few of them "unfair" or inconsistent with what I thought was the game's logic to that point, but these puzzles (or one example in particular, the (Spoiler - click to show)blue door puzzle, (solution spoiled within: )(Spoiler - click to show) doors in the light still affect their sister doors in darkness, so there is no real reason to believe that the color of light illuminating a door will affect its link. The other colored doors are always linked regardless of the light shone on them. Yet somehow colored light is enough to fix the broken link. ) might have been easier for those more familiar with the history of IF than I. The vast majority of the harder puzzles are highly stimulating and very clever, and the story is engaging and entertaining. I hope to see more from the Lavori d'Arcane universe in the future!
