level 13 in freedoom v0.6.3

I am stuck..I killed every possible enemy I could.There are a set of burning barrels I think I have to get past but I do not know how..I. already have the blue key,I got the bfg900 and I got the yellow skull key.I don't know where to go or what to do..If anyone can help I would be pumped..Thanks.

I do not think that one even has an exit. A few of the old Freedoom maps are definitely broken.

Download the latest 0.7 version, all maps are confirmed to be beatable.
