how does “after the previous selected one” work at the start? There is no previously selected on at that point, right?

I hoped the “starting from north” would fill that in.
I’m not sure what “starting from north” would mean exactly at the start, I could currently interpret this that the first time you go north or you go east. Not sure if this is actually an issue.

I like the idea, but I think there are some cases where it can’t be resolved. If Richardo has entered a dead end, what would “the first explored room in clockwise order after the previous selected one” be? The previously selected room would be the one he came from, and there’s nowhere else to go.

I don’t think that’s an issue, or at least it’s not an issue in my head (although I’m the one who thought of it).
If there’s only one way to go you always pick that one, you check the other 3 “options” first, see that those aren’t explored and choose the one you chose last time again.
Or you could think of it as a list of options, if there’s 2 options you switch back and forth, if there’s only 1 option you always choose that one.

Okay, so say Richardo goes north and enters a dead end, has only one exit, takes it, and ends up back in the room he was just in. Does Josh obey “starting from north” or “after the previous selected one” for deciding where to rotate clockwise from?

At this point you’re not concerned with the room you just left anymore.

“Starting from north” is there so you know which direction you should pick the first time you get to that room.
I was thinking if I should put something more elaborate about the initial conditions but I settled on this because it has to appear in the effect text for each room with it.

Ahh, so “one” is intended to refer to the previously selected direction, not the previously selected room. I think that’s too ambiguous for me, although I like the general idea of having a simple “keep your shoulder to the wall”-type procedure to replace the random one. 

Looks like this needs to be spelled out more clearly. You can always keyword it: have the feature as “Richardo von Nestor is disorientated. (+2)” and put a big paragraph somewhere else in the rules saying exactly what that means.

because I don’t fully understand this.
