Game itself gave no message
The idea of a "review" is to give your opinion on something, whether it's positive OR negative. It's naive and immature to mark anything negative with an "unhelpful" just because the person doesn't share your opinion. If they make a fair point, take it into account, don't be a self righteous dick. It's called "constructive criticism" and every kind of artist needs it.
On that note, the script at the end gave some interesting info on the situation in Cambodia, but the non game itself was a waste of time in my opinion and really acted as nothing more than a boring background for some heart string tugging music. Some of these kind of non games can be great and really make you think, but I think this one was a bit of a failure in that regard overall.
