Walkthrough

I can't get out of the well! I've killed all the spiders, I'm climbing the ropes, and it seems like the surface is almost within reach, and I've also found two hidden caches in the well. But I'm stuck here. The last hidden cache (pickaxe and sundial), I'm standing on the bridge and shooting at the logs at the top. But I can't reach the ropes :( Please tell me what to do?
