A truly exceptional co-op puzzle/escape-room style game. The entire series is fantastic.

This game is a major step-up in quality of puzzles, story-telling, and environment compared to the first three, especially noticeable upon entering maybe the most amazing / mind-bending puzzle room I've ever witnessed.

One or two of the puzzles are noticeably worse quality / harder to follow than the rest, made worse when it felt to us that the puzzle had become bugged (maybe it hadn't, though) BUT the sheer quality of the remainder of the game is high enough that these few experiences aren't enough to tarnish my overall experience.

It's not the longest game, but from my experience with this genre of games this is definitely on the longer side, and each game in the series has been progressively longer; I would not call the length of this game a downside. For the price and given the usual length of this genre, the length is perfect.
