The idea is that anybody can input their own button choice, and the player character will react to that decision. Unfortunately there is severe lag, which means it isn't an immediate reaction.
The creator of the channel is referring to this as a social experiment, wondering if a team of people can work together to beat the game. The more people that hop aboard however, the more challenging it gets.
As of now the stream has nearly 8 million views and almost 65,000 people viewing at any given time. After over five days of playing, the group currently has four badges and appears trapped in the Team Rocket hideout in Celadon City.
Some highlights of the stream have included the accidental release of Charmeleon due to struggles with the PC. On the other hand the team has managed the impressive feat of getting through Rock Tunnel, which is pitch black.
I joined into the hectic gameplay for a bit and have to say that it is frustratingly funny how tough it is to work through this game. I do like to think I played a role in saving Pidgeot, who was mere seconds away from being a victim of the PC.
If I had to guess I would say it will at least take a month for the game to get beaten. More than likely people will eventually get bored and leave, which would make it much easier to finish the game.
