Got it.
I don't know about the kiddy look everyone is talking about. The controls are streamlined, minimal, and pretty... is that kiddy.
But they are right one about the gameplay. I've only done the cell stage once but I can already tell I won't want to do it many times over. The same may be said about the Tribe game.
But, in the few hours I've played, I have had lot's of fun creating my creature and really that is what it's all about. Not as deep as I would have liked it, but still a good albeit casual experience.
