First off, to the people who think the game is "racist," you're either idiots, or trolls looking to stir up drama. In the 12 patients I saw in the game before deleting it, not one was white; but many were green, red, yellowish-green... some were animals. If you think a children's app with cartoon characters who are obviously not meant to be any race (& some not even human at all) is racist, then kindly get your head checked since you're not fit to be in normal society.
With that being said, the app is kinda pointless and hard to understand. At the bottom of the screen are a bunch of tools, but no indication as to what they are or what they do. In addition, there appears to be no wrong or right way to do things... which for today's coddled youth is the norm, I suppose; but if an option to solve a character's dentistry problems is ripping out all its teeth and replacing them with gold ones, I'm not so sure that's gonna alleviate any fears of the dentist that kids may have.
Would be far better with some guidance and a better portrayal of what dentists actually do.
