The only drawback are the eternal declarations. Not about how what works in the body, but what to do now. The first time helpful because you get along without guidance, but after the tenth time it just annoying. I play it only reluctantly, because several minutes is explained how to play the next game now and I have not found anything where you can shorten or cancel.
Nevertheless, I'm learning every time something to or setting my knowledge, which is not very good in this area ;-)
Due to the eternal game guides the pen of one recites I give only 4 stars ... with a tendency to forgive only 3 because it really bothers me. But it is for children and where it likes and does not interfere with it, so. 4
