I concur with veb. I was about to say the same.
Aside from that, the game itself is DAMN BORING. The creature creator was pretty cool, but the game mechanics plain and simply suck. They lack depth.
Body part bonuses, for example, don't stack.
I made a velocichicken kind of thing with two vicious claws. Then I decided it could do with four extra arms with equally vicious claws. Three times the claws -> three times the carnage, right? Wrong.
Never mind the fact that you have seven humongous mouths filled with rows of teeth; it bears no advantage over having one mouth full of teeth.
To be short: The creature design feature is largely cosmetic.
Now, I must admit that I haven't played past the tribal phase, but all in all, my experience so far has been very shallow.
Cell phase: Flow (the flash game)
Creature phase: Sort of like a dumbed down WoW, combined with Simon Says for those who take the vegetarian approach...
Tribal Phase: Sort of like a dumbed down RTS.
This is where I got bored and uninstalled. Talk about fuckin' overhyped.
