If you want fun. This is it. Update: The more that I play the more that I believe people under rate the game very much.
Music is in my opinion very good, not in therms of variety but to create that atmosphere of tension.
If you consider that you can get this game from Steam at $3.40 which I hope you can get, then you know we are talking about a bargain. If the offer expired those who are familiar with Steam know that is just a matter of few weeks or a couple of months to get it back.
Update:
Story is very good. Scenarios become richer, Voice acting is very good, the game get deeper as you advance, at the begining you may think it will gos low but really the way the game evolve during every level is amazing.
Again some of the games I own so you can have a reference for my critics.
