    I fail to see a logical path without bruteforcing. I had to resort to meta-logic at the bottom left (which gives a nice exercise in meta-ing 😛 ) Perhaps because of time pressure and the fact that this is Monday, so I switched off some advanced techniques, who knows.

      The puzzle uses one kind of step (connectivity without repeated shapes) just about everywhere. This makes it an unusual solve, but if you catch onto it a rather fast solve. The lower-left box may be the trickiest spot overall.

    Nice! My favourite piece of the puzzle has to be the 3×3 box at the bottom left.

    I don’t really like LITS puzzles, but this one was pretty fun because of the reliance on connectivity.
