Hmm...
Let me start by saying that this is better than the first one. However it still has several flaws.
First of all, looking at the items and the means to get them, I find it difficult to believe that a little more than a handful of people finished this without the walkthrough. I believe a good point and click should contain items that can be easily made using one's general knowledge. If not, there should at least be a clue in-game on how certain complex items are made. Seriously, most people would not know how to make a thermite bomb.
Second, the voice acting. The voice acting is unconvincing and does not have enough emotion. I could not feel that the guy I'm playing as really understands the situation he is in. The way he deals with the events is just as though he did those things everyday. And in the few cut scenes where he is actually in danger... His scream is just disappointing. And the saddest part is, he seems to have the best voice among all the characters in the game.
The graphics are just fine though. It suits the atmosphere. The secrets are also pretty good as several of them reveal an interesting backstory, which is fully explained in the timeline of events.
Overall, not the best, but one of the better point and clicks that appear here these days.
