I bought this a few days ago and just finished it. If you are looking for a puzzle game with decent logic puzzles you will find it here. Some puzzles towards the end I needed some assistance with but for the most part a sound logical mind will have no worries progressing through the majority of the story. Expect about 10 hours out of the game. The story itself didn't interest me much but I play for the puzzles anyway. If you enjoy the likes of Syberia and Myst you should buy
