That is a nice little garden you have there! I liked how the averaging and small mutations naturally lead to smooth, nice looking gradients of colours all across the board. I often saw flashes of bright colours that did not last more than a frame; I guess those were single plants that reproduce all around themselves and then got quickly averaged/taken over by their neighbours?

I was left a bit confused by the menu though: I was not able to edit any field other than the death chance (which I got stuck a few time on random high values, my bad T_T), and it looked like my cursor was still planting colours in the garden while I tried to click on those buttons.
