YES! Programmable critters! I really like that idea. Bummer that the visual customization didn't make it to the release build, but the game's already very pleasant to look thanks to the art style and animations. I also liked the sound effects for the animations and the soundtrack fits the gameplay flow nicely.
Maybe I messed something up, but towards the end the biomass acquisition slowed down by a lot for me and redoing critter configurations meant a ton of clicking. Wish I could save templates or cache the most recent config and subtract from there.
I hope the critters will thrive after we left...
