The fourth Blackwell game continues to make improvements over its predecessors in terms of technical polish. There is also a bit more depth to the puzzles and game play. This is still no where near the brutal difficulty of an old school point-and-click game, but it's nice to have more options in terms of combining inventory items, switching characters and querying your in-game search engine to advance the game. As usual, the story and characters are the highlight here, and the broader character arcs are starting to come to a head. There is one more game left in the series and I am anxious dig in to it soon.
