A great game to love and hate
Not to say this game is easy you will be getting much use out of the rewind mechanic from the level of difficulty some of the puzzles pose.
An all around good experience the price is the only issue i see to really gripe about but other than that the game, gameplay, and execution are superb. Note I said to hate as well, those of you out there who don't want to think or use your brain should avoid this game because your going to hate it for making you think.
A word of advice in this game if you see something or think something might work or do something go for it cause chances are your answer lies within.
