The only comments are positive ones, so it's not clear why some people didn't like this app at all. My guess is that they didn't understand it and/or didn't find it fun. Or maybe they were expecting fancy graphics and sound.

Maybe there's a way to discourage people who are not likely to give this app a high rating from trying it at all?
