Great puzzle game.

+ Great puzzles
+ Great mysterious athmosphere
+ Great "puzzle box" presentation of puzzles
+ Decently interesting story to explore, although not required, and although no clear resolution by the end
* Completed in 2 hours

On two occasions I checked for a solution of one step of the puzzle, but afterwards I did not feel it was unfair or not uncoverable.
