I'm searching for an eye. I left via the Daventry back gates and I closed them after I left. After looking around in the forest, I tried to climb back over the wall as I had several times before when helping the merchant. I can climb the first few steps (ie. straight up). When I try to climb to the up and left, however, the game doesn't let me. It shows a "Spacebar" prompt, but hitting the spacebar doesn't work. I can't find any other way to advance.
In case it's relevant, I have nothing my inventory except for one coin. I've talked to the people in the shops, but I didn't buy anything yet.
