About (summary)
Anatomical clicker. Start with one cell and create a whole animal! You will see what the body is made of from the inside, gradually growing bones, organs, skin and wool!
How to play
The main goal of the game is to create an animal step by step, collecting billions of cells. The game begins with the creation of the first animal out of 8 - a dog. As some part of the body grows, others will open. Cells are accumulating in a certain amount per second, depending on the lvl of improvements, for each click on the "cell" button, or you can buy them for virtual currency.
