Puzzle #85 - Loop and Shading? (Slitherlink)

This is not a Slitherlink puzzle. At least, not a normal one. This is a SLITSerlink puzzle. What's the difference? It's very simple- follow all normal Slitherlink rules. Additionally, the inside of the loop must be a valid LITS wall.

This puzzle is very difficult and requires some lookahead at points, but taking into account both the Slitherlink and LITS style deductions in combination does give a solution path that does not require bifurcation at any point. Ended up being too hard and people did bifurcate to solve in the showcase, and I placed second to last :/ I really don't know what people like.
