Pretty to look at, and interesting in a way, but totally random and senseless. Not really any good as a game, it's just random clicking and cross your fingers. No logic at all. Also, either it's too slow to respond, or things have to be placed too precisely. Even the person doing the video walkthrough had to try more than once to get some things to work. So even if you do something right, the game can miss it. I wish I could give it more than 2 stars, but I can't.
