I'm stuck at the point where the only things I have are a phone with a scanner, a phone with an empty inbox, and the red & blue dongles. I see a bunch of comments about "Put the phone up against the QR code" but that's not an option I'm seeing here
I'm giving up at the point where I need to contend with Spikes and Water at the same time. I can see how I need to proceed, but I'm not capable of actually managing it.
