It is not news that with the indie games gaining space a great number of different ideas or even jokes that for one reason or another get attention, become games.
The video shows one of this cases. It was a joke, then became a game and it is somehow growing. It is 2 player game where one player controls a baby walking inside a house trying to kill himself, by sticking his finger on a powerpoint, drinking cleaning products, drowing or whatever else, meanwhile the other player is the Dad trying to save the kid.
If are interested there is a free alpha version of the game to download right here.
Abd if you wanna know more about it I recommend this article from Kotaku.
