Actually, I just realized the map is keyed with a "W" instead of an "M". Unplayable. ;)
It's upside down, my man!
It’s keyed in the same direction as the gravity in that room 🙃 I wanted to use the key to reinforce the non-euclidian weirdness of the tower that you climb down towards the rooftop. I’m glad so many folks have been picking up on it!
Ah, that went right under my head!
