Small World Simulator by Rialgar

This is a zero player game. Or maybe a non-game. Anyhow, it is a simulation of a very small world that you can watch.
Tested only in Chrome, should work in Firefox. Will probably not work properly anywhere else.
I planned to add some interactivity, but instead it became an exercise in webworkers to get decent performance... oh well.

Bravo !
Its too bad you didn't have the time to add forms of interaction since this kind of thing is right up my alley. I'm not really sure what you would really add to this that isn't essentially a 'full game' on top of what you already have here.
Either way, you made something really cool even if at the end of the day it ended up not really being a game. Thanks for making it!
Some interactions would be great, but still, nice work :)
A more detailed rendering of this would make an awesome live wallpaper.
Some interactivity would have been nice so you could mess with it, but 48 hours disappears quickly.
Great work!

Maybe pole caps or other biomes would make it more interesting. Still a fun little toy.
I really like simulations and world generation via rng, and this combines them both! Could just watch this for hours...
