Neither! Nice try, Spidey. I'm not falling for the old, "open the doors clockwise or counterclockwise" trick. We'll first open the ones ortho to the one that's already open, then the one door that's para, then finally the two doors that are meta to the original door...
No wait, that's silly. So is opening all of the doors. We could just close the already open one behind us and not give away that the people who arrived in this room through the slide really like opening doors and killed the two maniacs in this room before opening all of the doors and then exploring, probably down the very door that the maniacs emerged from. On the other hand, that sounds like a lot of fun. For that matter, so does my configuration...
Alright then, the first door we'll open will be the door directly counterclockwise from the open door. Then the door directly clockwise from the originally open door. Next, we open the door that is opposite the original door. After that, there will be two doors still closed, and we'll first open the one that is two doors clockwise from the original door, and lastly proceed to the door that is two doors counterclockwise from the original door. That should throw off any clockwise/counterclockwise demons looking to trap us with their evil magics.
Of course, we'll probably be attacked by something before all six doors are open, but that's all part of the fun. Oh, and Cugel will check the doors for traps too.
