Yes, this is yet another backroute. Attached are two new versions:
- theresa.txt: A fix for geoo's latest backroute, which keeps the steel-mining to turn a lix.
- theresa V2.txt: A daring change that replaces the five steel steps with usual terrain. This prevents any turning by steel-mining, but allows freeing the blocker with the miner instead. I remember that in the NeoLemmix version möbius made the steps deliberately steel, but at the moment I cannot see a good reason for this, provided the platforms are very thin. Most likely I just overlooked a very simple backroute, but if this should by some miracle work, then I would prefer this version over the previous one.
EDIT: geoo found some more backroutes to theresa.txt, but the intended solution to theresa V2.txt. So if you want to try to backroute this level, please focus on theresa V2.txt.
