It's fun at first, but it lacks replayability.
The cell stage is mildly entertaining while you decide what kind of life-form you want to grow up to be (though I guarantee you'll pick Omnivore if you can help it).
While it's a matter of survival in your animal form, the game really feels fresh and new. In fact, I would've liked it more if the animal stage was a lot longer. The way you interact with other animals, the way you take on larger creatures or even epic monsters, the migration patterns of your herd and exploring the wide world is really fun and really engaging.
But after the animal stage, the game becomes a very basic, very lackluster real-time strategy game. The tribal and civilization stages are nothing more than mash-ups of Age of Empires and Civilization, the only bonus being that you get to design your stuff. There's nothing here that you haven't seen before, from three-choice politics to point-and-click control of armies comprised entirely of a single land vehicle type, which you will no doubt convert to a fleet made entirely of aircraft due to them not being limited as to where they can travel.
But the biggest letdown was the space stage. Instead of starting at one vessel and working your way to commanding a whole fleet with which to explore and conquer as you see fit, you're stuck with a single ship occassionally accompanied by a few brainless AI ships who are utterly useless against the more powerful space empires and tend to die pretty quickly. Oh, sure, you can upgrade that one ship, but there's no real sense of progress being made.
The graphics aren't that great, with everything looking about as well polished as that old CG television show Reboot, just with improved animation. If the textures and shapes were a bit more complex it might stand out.
I'd recommend this game only if it's on sale or free for a weekend, because it really isn't worth paying full price for this. It has enough juice for about 1 playthrough, but afterwards I really can't see any reason to go 'round again except to make different choices that will ultimately lead to the same result. But if you take the path of least resistance, you'll end up making the same choices each time.
Ultimately, it's a good concept, but the mid-to-late game mechanics really feel uninspired, like too much focus was given to aesthetic customization options rather than gameplay mechanics.
