If anyone's into sim-like games, here's a game based off of the 90's game SimLife:
http://scratch.mit.edu/projects/12988646/

It is a bit buggy / not up to par.
It currently features procedural generation and self-replicating life, as well as some music I've made.
I plan on adding features like consumption of food, natural selection, biomes, and other forms of life for the existing lizards to compete with.
The lizards as of now are sort of a placeholder for many other types of creatures.

Enjoy!
And, if anyone would like to give advice or contribute, go ahead. I'll be working on this once and while between school and the rest of life.

In the process of adding biomes. So far the map has a temperature system, and ice caps.
Lizards optimized to mate and lay eggs.
