The following are allowed (but not required): The basic rule is that you submit a demo/stream played at a particular difficulty level (HNTR, HMP, or UV) and you play without saving and reloading, ending your run when you die (or survive). Even if streaming, you can still submit a demo, if you want to.
If you are streaming, post a video of the stream. If you are creating a demo, post the demo. The rules are basically the same as they have been. If you tried to get to this secret, there would be no way back out. Unfortunately, the teleport line (which is how you escape from the pit on your way out) is close to the door, so the door is unable to open. The intent is that you go through this door and find a secret. If you drop into at the right spot, you will find a ledge that leads to a door. In the room with the barons there is a large pit.
