In this game, you go through a series of 7 rooms, each of which require you to complete a classic IF puzzle style. Rooms include a light source puzzle, a puzzleless puzzle, an NPC, and so on.
I found it to be hit or miss. I enjoyed the puzzles overall, though. I did use all of the hints, but the walkthrough was disabled, and so it was fun to try and make the intuitive leaps.
And the leaps are fun. I really recommend this for puzzle fans.
