Not really much here. Its fine overall. Only took me a bit under 3 hours to beat and while the puzzles ranged in quality, they were all over with quickly enough that the bad ones never stuck around long enough for me to get all that annoyed.

I guess its a fine way of killing a few hours. The atmosphere is nice and the puzzles are generally decent. The game's positives might not be particularly strong, but the weaknesses aren't particularly bad either.
