I've got a funky idea for the maps. What if monsters could apply exits? I can imagine some fun, when the monster you have been teasing follows you outside - imagine being chased by a Balrog around the city! At least monsters should follow you up stairs etc. I've noticed tons of people dropping down stairs, letting off all their mana and then applying the stairs again to regenerate. Maybe only single-square monsters that apply things (like vampires) could apply the stairs too and follow you.
