There are a ton of them. They just skin new animals and post the same game.

If you are looking for other incremental/clicker/idle games:
(On Kongregate)
(On Clicker Heroes Website, Armor Games, Kongregate)
Goat Evolution, Cow Evolution, and Platypus Evolution
(It's an app game for iPad and maybe other devices. Goat Evolution is the most involved of the three last I
checked, and all three are pretty similar.)
(It has a steep learning curve, but I've read it can be rewarding to play once you get the hang of it.)
