I thought it was pretty good, except for the fact that I finished almost the whole game in an hour. The only thing I have to do is the last puzzles, which are impossible.
I think it's a good game. No big deal, just another shooting game. It's easy, what makes anyone can play. Another game for the collection of addictive, only that this is not much, is to play one or two hours. Beyond all defects or bad things of the game is relatively good.
