Not even tech demo
This had potential for a lot of fun, but is bad for these reasons: to set up each round takes a very long time for the camera to recognise you actually exist. Also, whenever you lose a minigame, it's down to the camera's bad eyesight, not your lack of ability. But the thing is, these minigames are so easy and simple, only an idiot could possibly lose them- unless the camera messes up, which is often. You may need to wave to someone (wow, I can wave my hand!), or eat the food by chomping your jaw up and down.
All of the minigames are pointlessly easy, and I think Nintendo meant that to be the case because there is no high scores, and once the five minigames in whatever category you chose are over, that's it. The minigames are so few they are not randomly selected. At the end of each game, the video of you doing these actions is shown ,with photoshopping. It can be quite funny, but if you 'lost' a minigame, this appears broken. Also, the videos aren't even saved.
I would not go as far as to call Warioware Snapped a game. It's not even a tech demo, as it constantly fails to see you. This sort of thing can be played more reliably on a computer, with actual fun.
