Does its work well
I am glad you used an amoeba and not the regular human organism. If you did, I would be wondering why you would have a single celled creature like that with fully developed organisms around. It does kind of make you wonder why amoebas have never evolved beyond that. Of course, there are also sharks here, which has always been around. I was quite impressed at the huge variety of songs being used. This game was pretty fun to play and it was interesting to at least learn something about evolution.
