The concept for this game is very interesting, and for the first few levels it is very fun. But as the levels get more challenging, and more importantly as they get more crowded and have more moving objects, the limitations of the UI become very apparant. Half the time I fail levels it is because the game has done something unexpexted when I missed my mark by a pixel to the left or right. Objects also don't interact very naturally, and tend to fall or tip over on their own. Action points on objects often light up, but fail to properly attach. I've mostly given up playing this game, because I don't need to spend another half hour trying to attach a rope to a helicopter only to watch the character kick it down a hill instead of getting inside it. A little more thought and testing on the UI on this one would have made a world of difference.
