Unrelated to LD47, but I just finished a simple version of Game Of Life, as a tribute to the legendary John Conway.

The playable web version is here : https://hakro.github.io/godot-game-of-life/

And the source code is here : https://github.com/hakro/godot-game-of-life

It's made using the latest version of Godot (3.2.4-beta) which was released a couple of hours ago.

Cheers
