Man, I'm starting to regret not staying in school to get my PhD. This was neat. I learned that cannibalism is bad for sustainability.
Had a pretty good time. Made a bunch of little guys kill each other. Then I just created a utopia for one little guy and kept him as a pet. Very cozy.
I wish there was some more interaction to the game though. While the graphics and audio are great it does feel a bit boring just staring at the simulation after a while.
