First of all, what you need to know about this game is that the main character is going to be mike and he has some really bad problems that require a bit of attention. It seems that you are going to be his personal dentist and try to fix all his cavities really fast because he is in real pain. Make sure that you are going to understand all these concepts and that no one could ever back you up because otherwise you are not going to be making all these decisions in the right place. Be really fast and good at because mike is going to be there for you and you have to be really concerned about the things that you have to do. Try and pick up the medical gear and start fixing him because it seems that he has eaten too much chocolate and now his teeth are in problems of falling down.
