On Firefox here, the "Save Local Population" option seems to crash. Any idea why that might be happening? (Amazing site btw - every time it pops up I end up spending much too long with it).
As internet distractions go, the original was one of the most memorable I ever came across. A friend and I used to leave them running over lunch and see who was winning when we got back.
Thanks for the fun :-)
Still runs in the browser thanks to Ruffle:
