A labyrinth project I started some time ago, and never got on with.
the map contains 93 rooms with 2 to 8 portals in each, portal location is fixed, but I'd like to see you remember the exit point of even one of the 300 portals in there.
anyway, I don't invest enough time to make something out of this (my original plan was to make 9 of these, all with different portal setups, in a campaign so you could travel from one labyrinth to a different one that looks exacly like the first one.)
so I abandon this project and give my blessing to anyone with a good idea for this.
