Oh, a little cellular automaton-like game!  I'd say it's fairly captivating, so good job on that.  I think this one could be top-tier if it had things like genetic mutations (who doesn't like rooting for a unique thing?) or if cells had visual indicators of their state (they die for a reason, right?)... anything to give it more readily apparent feedback.  It's a bit hard to tell why something or why something isn't happening and it's not great to have to rely on the text under the program to kind of guess what's going on.  Oh, and the visuals are a bit mixed I think, the tiled background kind of clashes with the circular food and especially the cells which don't move very grid-like.  But overall for what it is I'd say it's a solid job.
