Fantastic work! I've tinkered with gamifying Game of Life in the past but never got it to work anywhere near this well, so I'm very impressed. Managed to beat every level without any hints but it took me a while. If you ever expand upon this (and I'd love to see it if you do), it would be great to have a play bar or something to scroll through the iterations to more easily see what happens on each step. Great stuff all around.
