It was an interesting and innovative puzzle game, I think there is a lot of potential in the concept.
My suggestion would be to make it longer and vastly more difficult. Despite the claim of about half an hour of gameplay it took me only a few minutes most of which was spent reading the story bubbles. And the greatest letdown was the difficulty, it has not proved to be a challenge at all, I hoped the difficulty would ramp up in the last few puzzles but it didn't or at least not enough to be satisfactory.
