UPDATE 2:
I've ported the game as Java Applet using Processing. It's not as good as original for 2 reasons, one I don't know java much, two it's not fun porting code and three I'm still fixing it.

I've tested with Firefox.

THE GAME:
The game is about a parallel universe where there are 5 species living in harmony, that we call as:
Huge, Big, Medium, Small and Tiny.

Each organism (of any species) has a certain lifespan, and at the end of it's life if reproduces certain number of children.

Now, as in every other world the resources are limited so no species is allowed to have more than 10 organisms.

And neither can there be 0 organisms for any species.

You are their God, and it's your duty to keep the harmony intact by eliminating extra organisms of any species or avoiding any species to extinct (don't kill the last member of any species)
