Could be some kind of bug since I remember removing one in the later version but I don’t know if it already existed in this early version. But it could also be that the structure of the dungeon is not that intuitive. The dungeon is different every time and the layout of the rooms is basically a tree structure, so there should be no circles … it’s more like the corridors connecting the rooms can be different in length. Going NORTH→EAST→SOUTH→WEST does not mean that you went in a circle.
Not like this: | More like this: | ####### ####### | ####### ####### # # # # | # # # # # 2> ....... 3 # | # 2> ....... 3 # # # # v # | # # # v # ###:### ###:### | ###:### ###:### : : | : : : : | ###:### : : : | # ^ # : : : | # 1 # : ###:### ###:### | # # : # ^ # # # | ####### : # 1 5....... <4 # | : # # # # | ####### ###:### ####### ####### | # # # # | # 5 ....... <4 # | # # # # | ####### #######If you have have problems finding your way through the dungeon you can try to always stay at the right or at the left wall. This also works in most normal labyrinths (but not in labyrinths with circles).
