Whether we speak of steam or smartphone version of it is no doubt this game is good, we take pleasure in designing disease. Mobile version loses visual apps that can be quite appealing on PC, I think viseuls including bacteria, diseases, etc .. advanced -1 star for that side. And yet -1 star for the dark side of this game ... The in-app purchase, I feel that to enjoy all the features of the game I have to spend 30 easily, especially once buy all this pretty content, I find that the life of the game become shortened. Indeed you'll find yourself doing the scoring and not playing to unlock features for free. All in all good game but in-app purchase too far.
