I stumbled upon this forum when looking for an explanation for some puzzles of the 11th hour and I had to say something about this game.
First of all, games with tons of video content and a thick plot have never been my thing and the only thing that attracted me to the 11th hour was the puzzles. And I remember having a blast solving them. Some of them didn't seem to have patterns and I still don't see a way to logically solve the pool balls riddle.
However the furniture riddle was dynamite. Solving it required extreme patience and thinking. A similar game was later made in Flash (not me).
The knights game was awesome too. I liked it so much I made it in Flash with dynamic piece arrangement. Check it out:
