Agree, kudos
Great app! Like others, however, I would suggest some way to keep track of lineages, also maybe manipulate what determines what traits protozoa look for in a mate (other than being the closest one)? Perhaps a way to "tag" and then follow a specific protozoa and its progeny. Whatever you can add will be happily accepted - designers clearly did a brilliant job and will surely be thinking of things I cant on the spur of the moment!
If you are in doubt, buy this app. Really.
