If this happens to anyone else, please press the space bar to continue. The cut scenes seem to not play in certain browsers (Firefox). If you continue like this, it is likely the tablet will not display the Twitch streams but rather a white box. The ending cut scene will also not play (press space to skip that too).
If you want the normal experience please try the game on Chrome. I tried for around 7 hours to find a fix for this, but I couldn't find anything about it.
