Nice! Finally a game completely without violence. It's beautiful. I think there is a lot of potential in the genetic pairing aspect. Maybe the children of the children could also cross their genes, without it being incestuously weird of course? :-) Maybe with some Conway's Game of Life aspect to it and the player trying to cultivate the perfect genetically pure flower arrangement, without it having a weird Nazi-esque touch with social-Darwinistic flavour of course? I'm all game for the Game of Life implementations, here is my go on it for the iPhone: https://itunes.apple.com/au/app/apeiron/id1076025560
PS: I just had a look at your code and I also like a lot that it's all SVG generated graphics, endlessly scalable and basically no loading time at all and still very charming aesthetics.
