Did you interact with the first paper? That's what sets up the next events.
Thank you for playing!
Hmm, well I'm not sure how I can help you, as I have no idea what's wrong. You have to walk through a few loops before the paper appears. Do NOT interact with it before it's unhidden, that would break it. I left it there because why would people interact with nothing? It makes no sense. But I will change that in a later patch for sure.
Worst case scenario, you could watch a youtube video or something. I don't want to spoil it though, that would suck.
