revival activity determines what proportion of cells is revived every time a revival occurs. Revival means cells become active again, which also means they have a chance to just die if there's too many of them. edge to edge teleportation determines whether they go through one edge of the map to the other H to toggle UI overcrowded population determines how many cells do there have to be for every cells to start dying from overpopulation
I was making sprites for a game, when I started experimenting and it turned into a fully fledged simulation. Colors are semi-random, since I messed the code for them up. Unless scratch has some special rules for licensing, i'm gonna license the cell sprites as CC-BY so credit and use wherever, including outside of scratch if you want.
