I have to say it as not worth me having to restart the game so many times. I did not care too much for the music, I would have liked a mute button. Aslo, really easy and boring puzzles, where the hardest part is just figuring where to drag stuff. I also found the ending kind of lame. It's a shame, because this really is a great concept for a game, just not executed that well. I feel like if you were to expand the game, in length and variety, you could make a fantastic game.
I will give a hints, the information on the second level is all pertinent, except for one; the nuclear symbol is important; the boxes are a red herring, look for everything you can change.
