I think it's a bit unfair to attack these sort of "games". Sure they can be different and you can hardly call some of them games at all. But it's good to have people branching out and trying different approaches to having interactive media.
One thing I can agree with here though is the fact that you can only click sad, which happens all too much in things that try to appeal to a "deeper thinking" sort of thing. So in that sense I can agree, people have caught on that this is a new thing to try out rather than a typical game. But some people make them focusing too much on one range of emotion, which tends to be sadness, depression, whatever. That needs to change.
But until then keep an open mind when it comes to this sort of stuff. Sure half of it may not have gameplay or even may not have much of a point. It's all about experimentation, some people aren't as great at it, but some people discover new things through creating with more variety. The good thing you can say about it is people are trying new things, rather than constantly spewing out "casual" games and stuff we've all seen before. Unless of course these start overpopulating and we have to move on to some other new thing. Eh, it's a cycle of progress. There's always something for people to complain about.
