Overall a very enjoyable game. The voice acting is not bad, the castle and surroundings are really well drawn and you can explore extensively, the story is pretty good and your character is a fine, decent fellow.
The puzzles are mostly straightforward (a few are not intuitive at all, however). It has suffered a bit from being adapted from PC - the interface is a little stilted and static at times - but it is good for several hours of mildly challenging and entertaining play.
There are a couple of timed puzzles but even I, who am no good at timed and reflex based puzzles, was able to complete them without much stress.
