You can actually go left or right when your inside. So instead of just going straight, take one step to go inside then turn left or right.
i tried that it didnt work and therse not another door
uhh enter the other way such as thisamity square enter 1----------------------amity square enter 2go to the other door thingy mabober
if there is another door where is it
if i remember correctly if you keep going to the right in the ruins then you should keep teleporting to a different one and left takes you to the original one you entered
i figured it out thank you any way
