It is a pay to win system. Be prepared to wait hours (ie 5+ hours) of your life watching a stream in order to be moved up a queue (or entered into a 'raffle') only to be continually ignored in favour of people willing to dump money. It is not worth the wait, you'll be forced to watch hours of absolute garbage just for a couple of minutes of feedback from someone who doesn't care about you, your time, or your game. The people watching in chat are also not there to see your game, they are in the same boat as you, just hoping that you get fed up and leave before they do so they don't have to stick around longer.

AVOID LUDUM DARE GAME STREAMERS LIKE THE PLAGUE!
