Everything about Id|le is documented there, the creatures, their family trees, the way naming works, their abilities, the environment and music controls, the operator, and pretty much every feature of the sim
Oh, and a fun feature to play with, pull in content from any website to be fed to the creatures: http://id-le.com/?from_wiki=https://en.wikipedia.org/wiki/Y_...
(the above param only works for wikipedia links, but you can load up any website from inside the Studio > Feed the world feature onside the sim)
