Hi Leo,
Really awesome game you have created. If I ever get an office I'm hanging a screen with this game on the wall instead of a stupid painting. : )
A feature I would really appreciate is a save button. I have tried to let it run for several hours to see what colony develops and I find that really cool but I can't let it run for ever and right the colony just vanishes which means there is no way to ever let it run for years on end (sped up) which would be necessary for actual intelligent behaviors to develop.
Super cool stuff you are doing!!!
