The same level as First Move 2, functionally. Having played that level first, I am not a fan of this sequel. Now that David is a much more skilled puzzle designer, 14 years later, I would love to see him fix this level for good and get the intended path working!
OK, I give up, you win. :) Though I know all three paths, don't know how to fix this. Intended path: LUUULRDDLDUULDDDRU
UUUULDDDDDRDLRDRRR
RUUUULLLLDLURULLLDR
RURDDDLDRRRLLUURD
