In this game there's small brown boxes where there is baby bacteria inside and when you put two identical bacteria together then it forms a new bacteria. 🦠🦠🦠👋

Fine game, but when I spend diamonds on the "deals" for some reason I don't receive half of them. The newest deal had the color option peridot + two others for sale, I bought it with the gems, and I still don't have peridot (it says I have to get it still- has "try" not "use" on it) it's disappointing and it has no recourse afaik
