Shadow man is a good game but the problem with this game is you get lost very easily. I never ended up finishing this game, I played 20 hours of this game and got lost at the 15 hour point and was wondering around for 5 hours before giving up on it.
The game has a lot of back tracking, you need to find items to unlock previous areas, the problem is half the items you collect you don’t know what to do with them.
