Awesome. Is there a collection of GoL implementations? It would be impossible to be exhaustive, but I've been collecting them and I'd love a resource that makes an attempt to document as many as possible.
I don't know about an existing list but I created a unique implementation a while ago that I'd like you to add to your list. It's available at https://congol.net and the source is at https://github.com/lukew3/congol. Pretty similar to lifecompetes in that it's a multiplayer game of life, but is designed specifically for two duelling players.
This isn’t quite what you’re looking for but I have a GitHub project to create various implementations, including for ethereum!

EDIT: perhaps the GitHub’s main README could include links to various implementations too!
