I'm in the main crypt. Due to various misadventures, one of my characters was dead and one was cursed when I faced the two Spirits. They then killed two other of my characters. I definitely can't kill them. Running away only delays the problem. Is it true and intentional that there's no way back to town? Do I have to Revert Adventure and do this all over again?

Hmm. I'm pretty sure, in fact positive, you can go back to the first room, flip the switch, and run for your life back to town.

u can always get out of the dungeon u are in, just make it the way back, about ur character dying, why dont u start back at the last point u have saved? or maybe u should save more often!
