Well, I feel like a horrible person after hearing all of those mice dying. I love the ethical dilemma in the game. If you're goal is to maximize happiness you have to increase the mouse population and keep them all well fed. Of course, this is hard to sustain and failure results in an enormous amount of suffering. Is the risk associated with maximizing happiness worth it when the cost of failure is so high? Maybe by attempting to have a satisfactory amount of happiness in the world we are we are more likely to actually maximize happiness.
The art for the mice was great, as was the design of the ui. My only complaints are (i) I wish everything moved a little slower and (ii) the sfx for the eating got a little out of hand when there were a lot of mice.
