This game is highly rated, which is why I tried it. It is fairly short, and has two difficult puzzles, as well as some trouble at first until you realize that you have to examine every object in the room (okay, maybe it' s just me).
The first puzzle (involving a sequence of numbers) was very ingenious. I thought at first the answer would involve some experimentation, but it was all very logical in the end, though I didn't solve it myself.
The second puzzle is a bit more obscure, but fun.
Altogether, it is not very long, and I would recommend it only to puzzle fiends. Those who are into intrigue may find it worthwhile to skip the two puzzles via walkthrough.
