I got this game on sale for 50 cents, but would not recommend it even if it were free. As a puzzle box game, it relies too much on the use of keys. The puzzles have too many impossible contraptions that ruin the suspension of disbelief. If the complexity were desaturated, it would feel much more authentic. As it is, the combination and pattern based puzzles are just too easy. The story is unenthralling and becomes more watered down in the second game. Save your time if you are looking for a good puzzle, because most of this game is simply looking for the right hidden spot to click.
