An ambitious project that misses a few things here and there, but makes it worthwhile and engrossing for the time spent.
Now let's get to the good. The puzzles are inventive your first time through them and they make you think. It is a smart game overall and the mood never really leaves you. The tension doesn't leave either as from early into the game till the end you will always have to be watching out for traps especially trip wire activated shotguns. Instant death traps like these are always around the corner. You never really feel safe and that is a plus. The mood and atmosphere are almost that of Silent Hill. The game does feel different though and is true to the Saw movies. It features many characters from them including the protagonist Detective Tapp. The voice acting is great and the story is enough to make you want to play on without becoming overbearing. I cannot stress enough about the tension and mood and how well they are played out.
So all in all it is a great first attempt at something new. Hopefully they make improvements to the formula and don't give up because of mixed reviews. It's worth a rent for sure, but with little replay value and such some people may be satisfied with just that. It's a solid, but flawed experience you will not soon forget.
