2/18/2016 - Not quite sure when I posted the below announcement, but now it has not just changed - apparently it is gone forever. What a shame - such a beautiful game and wonderful community!  I've read they are trying to build another one, but since the owner isn't part of it, they have to go with something else, obviously.
UniCreatures has changed!  I just found it out and I'm not sure how I feel about the change.  Quite frankly, it doesn't look near as nice as it once did. I'll withhold judgement on how I like the functionality until later.

UniCreatures - UniFaction (their forum site)

See more avatars under
UniCreatures is a very well thought out game, The object is to collect, organize, and  maintain the creatures. After collecting one of each stage of the creature and one male and female, you can then start collecting them in quantity. When you do this, the game allows you to add them to what they call "herds". You can add any stage of the creatures except the egg stage to its herd. Adding the creatures to a herd means you no longer can do anything with it and some of the creatures all turn the same color.

When you click on a creature you have three options:
  • Feed Pet
  • Play With Pet
  • Care For Pet

By clicking one of these options you give that pet another Evolution Point. After a fixed number of points, the creature is ready to evolve into the next stage. When you have evolved the creature to the last stage for the first time you earn one more energy point. (I think its called energy - correct me if I'm wrong!)

The artwork there is a different style than at Flowergame, but just as good.  They come out with a new creature every month, along with new "clothes" you can "dress" your avatar (avi).
