Very simple concept, but it works.
The characters have just enough detail in their portraits that it's possible to identify them in a crowd. I was surprised to notice that my most likely score was 75%. I suspect this has to do with the combination of the amount of time available and the fact that the human mind struggles remembering more than 3 details simultaneously without creating some form of gimmick reminder rule. I would have preferred to have an explicit timer. This has two advantages: it builds tension as we go along, it removes the surprise when the screen changes.
The game is obviously aimed at a younger audience, and that's great, however, I still think it could use more variety to improve its longevity, which, at the moment, is extremely short.
There is no audio at all.
I don't think the theme was followed at all.
Good show. Simple, humble, functional, fun.
