it's ok - decent concept but not all that interesting. If I had not already seen the physics engine, I would have found the game unique, but as I have seen the physics engine before (several times) it becomes just more of the same. Replayability and entertainment factors hurt the score.
Took a 2nd look and I still feel that this game was a waste of my time. There is no real point to your choices except the final score. There are no consequences for those choices... as I stated before - POINTLESS.
The first game got tedious after a while and now they add more? It is well executed, but there is nothing new to the game in the expansion and, at least for me, it feels like it is lacking something to help make it a replayable game.
On the positive note, the controls are very responsive providing a lot of character control, and the graphics really protray the game's atmosphere well.
